libplatsupport,imx: Remove all timer constants

Now that the addresses of the registers and the IRQ numbers are being
read from the DTB, we no longer need these constants.

libplatsupport,imx: Move HW ops to driver level

Timer resource initialisation and the management of interrupts should
belong in the driver level and not the timer abstraction level. This
commits moves those operations down into the driver level for the i.MX
platforms.

platsupport: remove static init in ltimers

The regular init functions can be used with an implementation of
ps_io_ops_t that is a static implementation

sabre: add missing include

this defines static_timer_params_t

imx/ltimer: Moved static_timer_params_t defintion

Moved the definition of static_timer_params_t to
imx/platsupport/mach/timer.h. This allows other imx machines
to use the static_timer_params_t struct.

platsupport/imx: Implemented ltimer_static_init

Created an ltimer static init function. This allows the user
to pass in pre-mapped vaddrs for the timestamp and timeout
timer devices.

Generify i.MX timers

This commit splits out imx timer functionality to remove the #ifdefs for
i.MX7. This is driven by the need on the RT kernel to use two EPITS
instead of an EPIT and GPT for the user level timer drivers, which makes
all the i.MX timers similar, in that they use a timer for timeouts and a
timer for the time, but different in that they all use different
combinations of timers.

plat/imx7: add initial support for imx7 SoC

trivial: use pragma once
