Current implementation of LCD and backlight power control functions
is not complete, as result PDA consumes power in suspend.
Fix this issue by managing state of some latch bits, just like
WinMobile does.

This patch changes VMALLOC_END from 0xE0000000 to 0xF6000000, because
some systems want to use more vmalloc()/ioremap() area and now don't use
from at 0xE0000000 to 0xF6000000 (the start of Samsung SoCs' VA space)

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.
The various declarations were removed using the following script:
grep -rl MACHINE_START arch/arm | xargs \
sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'
[ Initial patch was from Jeremy Kerr, example script from Russell King ]

Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.
This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.
