* Introduce CONFIG_BATTERY_MEASURE define, to allow targets (application)
to break powermgmt.c's assumption about the ability to read battery voltage.
There's now additionally percentage (android) and remaining time measure
(maemo). No measure at all also works (sdl app). If voltage can't be measured,
then battery_level() is king and it'll be used for power_history and runtime
estimation.
* Implement target's API in the simulator, i.e. _battery_voltage(), so it
doesn't need to implement it's own powermgmt.c and other stubs. Now
the sim behaves much more like a native target, although it still
changes the simulated battery voltage quickly,
* Other changes include include renaming battery_adc_voltage() to
_battery_voltage(), for consistency with the new target functions and
making some of the apps code aware that voltage and runtime estimation
is not always available.

We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+
Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

lcd_write_data() wrote twice too much pixels to the controller
The fix is the same than r22885, vertically packed 2bpp displays use
8-bits fb_data while horizontally packed 2bpp use 16-bits fb_data

Remove unused lcd_mono_data
Replace a loop in partial update function by asm lcd_write_data()
Remove a variable only used in this loop (x) and rename x0 to x
