i2c-pnx: Enable clocking only during transfers

To help reduce power usage during non-I2C transactions, setup I2C
clocking to only come on when an I2C transaction is in progress or
when the I2C peripheral registers need to be accessed.

ARM: LPC32xx: Suspend code tweaks

Fix issue with PCLK loss when switching from run to DRUN mode by
forcing PCLK divider to 1 prior to switch. Disable stop mode bit
early in system bring-up.

serial: LPC32XX_hsuart: More spinlock issue corrections

tty_flip_buffer_push() should not be called in locked context.
Removed locks for some functions that were already called with
locks enabled, added locks for some that should be locked.
Added lock for _startup for safety.

RTC: LPC32xx: Improve RTC invalid state detection

When a power cut of few seconds occurs (time depending on the board power
stage), RTC SRAM can be corrupted. When the RTC voltage starts to deteriorate,
bits in the RTC register change state. But if the key register stays valid and
other bits in the RTC like the up/down time change and the system is repowered
on with the key register still valid, the software will think the RTC is ok.

In these cases, you can see some weird dates like 2035, 1982, ...

This patch uses the down counter value to validate the up counter one (it must
be equal to u32 inverted up counter value). If values don't match, it reset
both counters.

ARM: LPC32xx: Fix mutex lock issues got clock driver

On some cases, the clock drivers could grab a mutex twice in an
improper context. This patch changes the mutec mechanism to a
simlpe irq lock/unlock mechanism and removes un-needed locks from
some functions.

ARM: LPC32xx: Fixed structures improperly tagged with __init

Several platform structure related to NAND were improperly tagged
with the __init flag and were cleared after init. When modules or
functions that examined the platform data list were used, the system
would crash. This patch fixes that.
