IB/ehca: MR/MW structure refactoring

- Rename struct ehca_mr fields to clearly distinguish between kernel
  and HW page size.
- Sort struct ehca_mr_pginfo into a common part and a union containing
  specific fields for physical, user and fast MR

md: change bitmap_unplug and others to void functions

bitmap_unplug only ever returns 0, so it may as well be void.  Two callers try
to print a message if it returns non-zero, but that message is already printed
by bitmap_file_kick.

write_page returns an error which is not consistently checked.  It always
causes BITMAP_WRITE_ERROR to be set on an error, and that can more
conveniently be checked.

When the return of write_page is checked, an error causes bitmap_file_kick to
be called - so move that call into write_page - and protect against recursive
calls into bitmap_file_kick.

bitmap_update_sb returns an error that is never checked.

So make these 'void' and be consistent about checking the bit.

OMAP: add TI TWL92330/Menelaus Power Management chip driver

Add Texas Instruments TWL92330/Menelaus Power Management chip driver.  This
includes voltage regulators, Dual slot memory card tranceivers and
real-time clock(RTC).

The support for RTC is integrated with this driver only; it is not separate
module.  Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic"
(1/N second) IRQs.  System wakeup alarms (from suspend-to-RAM) work too.

(rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will
behave as expected.

fb: epson1355fb: kill off dead sh support

The SH board that was the only user for this code was removed entirely from
the kernel quite some time ago, so there's no reason to leave the stubs in
place.  Additionally this driver was completely broken anyways, so there's
not really a lot of point in fixing it up either.

I can't imagine that this driver gets any testing on ARM either, given that
FB_BLANK_UNBLANKING doesn't exist, and kills the build regardless of which
platform is compiling.  This fixes that, too.

It wouldn't be a lot of work to finish the platform device conversion and
go with a generic 8-bit read/write_reg and kill off the architecture
dependence completely, should someone have any use for this driver.
