time: Import time_after64() and friends from Linux

When using us times it makes sense to use 64bit variables for storage.
The currently implemented time_after() and friends functions only handle
32bit variables. This patch now includes the 64bit variants as well
from Linux. This will be used by the upcoming generic cyclic function
infrastructure.

These macros were copied from include/linux/jiffies.h of Linux 5.18.

timer: Allow delays with a 32-bit microsecond timer

The current get_timer_us() uses 64-bit arithmetic on 32-bit machines.
When implementing microsecond-level timeouts, 32-bits is plenty. Add a
new function that uses an unsigned long. On 64-bit machines this is
still 64-bit, but this doesn't introduce a penalty. On 32-bit machines
it is more efficient.

timer: Allow delays with a 32-bit microsecond timer

The current get_timer_us() uses 64-bit arithmetic on 32-bit machines.
When implementing microsecond-level timeouts, 32-bits is plenty. Add a
new function that uses an unsigned long. On 64-bit machines this is
still 64-bit, but this doesn't introduce a penalty. On 32-bit machines
it is more efficient.

timer: Allow delays with a 32-bit microsecond timer

The current get_timer_us() uses 64-bit arithmetic on 32-bit machines.
When implementing microsecond-level timeouts, 32-bits is plenty. Add a
new function that uses an unsigned long. On 64-bit machines this is
still 64-bit, but this doesn't introduce a penalty. On 32-bit machines
it is more efficient.

regmap: fix regmap_read_poll_timeout warning about sandbox_timer_add_offset

When fixing sandbox test for regmap_read_poll_timeout(), the
sandbox_timer_add_offset was introduced but only defined in sandbox code
thus generating warnings when used out of sandbox :

include/regmap.h:289:2: note: in expansion of macro 'regmap_read_poll_timeout_test'
regmap_read_poll_timeout_test(map, addr, val, cond, sleep_us, \
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

drivers/spi/meson_spifc.c: In function 'meson_spifc_txrx':
include/regmap.h:277:4: warning: implicit declaration of function 'sandbox_timer_add_offset' [-Wimplicit-function-declaration]

This fix adds a timer_test_add_offset() only defined in sandbox, and
renames the previous sandbox_timer_add_offset() to it.

time: Import time_after64() and friends from Linux

When using us times it makes sense to use 64bit variables for storage.
The currently implemented time_after() and friends functions only handle

from Linux. This will be used by the upcoming generic cyclic function
infrastructure.

timer: Allow delays with a 32-bit microsecond timer

The current get_timer_us() uses 64-bit arithmetic on 32-bit machines.
When implementing microsecond-level timeouts, 32-bits is plenty. Add a
new function that uses an unsigned long. On 64-bit machines this is
still 64-bit, but this doesn't introduce a penalty. On 32-bit machines
it is more efficient.

drivers/spi/meson_spifc.c: In function 'meson_spifc_txrx':
include/regmap.h:277:4: warning: implicit declaration of function 'sandbox_timer_add_offset' [-Wimplicit-function-declaration]

This fix adds a timer_test_add_offset() only defined in sandbox, and
renames the previous sandbox_timer_add_offset() to it.

time: Import time_after64() and friends from Linux

When using us times it makes sense to use 64bit variables for storage.
The currently implemented time_after() and friends functions only handle
32bit variables. This patch now includes the 64bit variants as well
from Linux. This will be used by the upcoming generic cyclic function
infrastructure.

These macros were copied from include/linux/jiffies.h of Linux 5.18.

doc: replace @return by Return:

Sphinx expects Return: and not @return to indicate a return value.

timer: Allow delays with a 32-bit microsecond timer

The current get_timer_us() uses 64-bit arithmetic on 32-bit machines.
When implementing microsecond-level timeouts, 32-bits is plenty. Add a
new function that uses an unsigned long. On 64-bit machines this is
still 64-bit, but this doesn't introduce a penalty. On 32-bit machines
it is more efficient.

common: Move get_tbclk() to time.h

This function related to timer and most of the timer functions are in
time.h, so move this function there.
