ARM: 9049/1: locomo: make locomo bus's remove callback return void

The driver core ignores the return value of struct bus_type::remove
because there is only little that can be done. To simplify the quest to
make this function return void, let struct locomo_driver::remove return
void, too. All users already unconditionally return 0, this commit makes
it obvious that returning an error code is a bad idea and ensures future
users behave accordingly.

ARM: 8217/1: sa1100 collie: use gpio-charger instead of pda-power

Use gpio-charger driver instead of pda-power: it automatically cares
about used gpio and since collie does not differentiate between usb and
ac chargers, pda-power is an overkill for it.

As a bonus this allows us to remove gpio_to_irq calls from machine init
call - it is fragile. These gpio_to_irq calls will fail if gpios are
registered later, via device driver mechanisms.

ARM: delete struct sys_timer

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7.

Conflicts:

scripts/mod/file2alias.c

This change is wrong on many levels. First and foremost, it causes a
regression. On boot on Assabet, which this patch gives a codec id of
'ucb1x00', it gives:

ucb1x00 ID not found: 1005

0x1005 is a valid ID for the UCB1300 device.

Secondly, this patch is way over the top in terms of complexity. The
only device which has been seen to be connected with this MCP code is
the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same
driver. Adding a match table, requiring the codec string to match the
hardware ID read out of the ID register, etc is completely over the top
when we can just read the hardware ID register.
