Change the way the UART state is saved over suspend to allow the s3c64xx
code to modify the settings on resume to avoid any illegal state changes
to the UART clocks. This will also allow us to save the UDIVSLOT register
on newer SoCs.

Move to using a structure for the UART use the extant Kconfig configuration
specifying the number of UARTs.

Rename s3c2410_cpu_resume to s3c_cpu_resume and s3c2410_cpu_save to

which are now in the generic PM code.

Since we have moved a large proportion of the PM code to the common

There's a bug in calculation of IRQ_EINT_BIT introduced on the test
branch for pm changes for s3c by Ben Dooks fixed in this patch.

There's also a bit of a mystery about how wake gets to wake EINT
set of interrupts, I added a couple of lines that make it work for
EINT4+ but not sure what's meant to be there for EINT0-3.

Still, this gets GTA02 resume working again.

The cacheid_init() function assumes that if cpu_architecture() returns
7, the caches are VIPT_NONALIASING. The cpu_architecture() function
returns the version of the supported MMU features (e.g. TEX remapping)
but it doesn't make any assumptions about the cache type. The patch adds
the checking of the Cache Type Register for the ARMv7 format.

This reverts commit 155b25bc, which was
totally wrong - the "embedded" options still exists (very much so) even
on non-embedded platforms.

It's just that we don't bother with actually asking about them when
we're not embedded, we just take their default values (which is usually
'y' - the options add features that may not be worth it in a constrained
environment).

This is done by
1) Wake up lock waiters when we close the master file descriptor.
   Not when the master structure is removed, since the latter
   requires the waiters themselves to release the refcount on the
   master structure -> Deadlock.
2) Send a SIGTERM to all clients waiting for the lock.
   Normally these clients will get a SIGPIPE when the X server dies,
   but clients may also spin trying to grab the DRM lock, without
   getting any sort of notification.
