Based on Aaro's previous fix, this needs to be fixed for the newly added
remap_off and remap_sleep resources as well.
The code tries to skip values initialized with -1, but since the values
are unsigned the comparison is always true.
The patch eliminates the following compiler warnings:
drivers/mfd/twl4030-power.c: In function 'twl4030_configure_resource':
drivers/mfd/twl4030-power.c:338: warning: comparison is always true due to
limited range of data type

The <RESOURCE>_REMAP register allows configuration of the <RESOURCE> in case
of a sleep or off transition.
Allow this property of resources to be configured (through twl4030_resconfig)
and add code to parse these values to program the registers accordingly.

Describe how the resource registers are laid out and the various bit-fields in
them.

When the sleep script is loaded before the wakeup script, there is a
chance that the system might go to sleep before the wakeup script
loading is completed. This will lead to a system that does not wakeup
and has been observed to cause non-booting boards.
Various options were considered to solve this problem, including
modification of the core twl4030 power code to be smart enough to
reorder the loading of the scripts. But it felt too over-engineered.
Hence this patch just warns the DPS script developer so that they may be
reordered in the board-code itself.

The TWL4030/5030 family of multifunction devices allows board-specific
control of the the various regulators, clock and reset lines through
'scripts' that are loaded into its memory. This allows for Dynamic Power
Switching (DPS).
Implement board-independent core support for DPS that is then used by
board-specific code to load custom DPS scripts.
