For some platforms, it is inappropriate to register all PXA UARTs.
In some cases, the UARTs may not be used, and in others we may want
to avoid registering the UARTs to allow other drivers (eg, FICP) to
make use of the UART.

In addition, a while back there was a request to be able to pass
platform data to the UART driver.

This patch enables all of this by providing functions platforms can
call to register each individual UART.

 2. By vendor name in alphabetic within each category

Adding in a printk, so that the user knows why acpi-cpufreq refuses to
load.  Also, once system is blacklisted, don't repeat checks to see if
blacklisted.  This also causes the message to only be printed once,
rather than for each CPU.

This will fix some small issues with the COH 901 331 RTC driver:
- Interrupt is disabled after alarm so that we don't fire
  multiple interrupts.
- We return 0 from the coh901331_alarm_irq_enable() ridding
  a compile warning.
- We alter the name in the U300 device registry to match that
  of the driver so they sucessfully resolve.

   passed so we goto repeat.
2. Nothing updates nextstamp (only updated if the timeout is in the future
   And we just decided it is in the past)
3. At the end nextstamp still has the same value so it is still valid and
   in the past.
4. This repeats until read_c0_count has a value which causes nextstamp to
   be in the future.

Since commit 22242681 ("MIPS: Extend
COMMAND_LINE_SIZE"), CL_SIZE is 4096 and local array variables with this
size will cause an build failure with default CONFIG_FRAME_WARN settings.

Although current users of such array variables are all early bootstrap
code and not likely to cause real stack overflow (thread_info corruption),
it is preferable to  to declare these arrays static with __initdata.
