This patch renames function names like twl4030_i2c_write_u8,
twl4030_i2c_read_u8 to twl_i2c_write_u8, twl_i2c_read_u8
and also common variable in twl-core.c

The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030
for OMAP3. The common modules like RTC, Regulator creates opportunity
to re-use the most of the code from twl4030.
This patch renames few common drivers twl4030* files to twl* to enable
the code re-use.

The gpio_twl4030_probe() function calls gpio_twl4030_remove(), and the
former has __devinit, so the latter cannot use __devexit. Otherwise we
hit the section mismatch warning:
WARNING: drivers/gpio/built-in.o(.devinit.text+0x71a): Section mismatch
in reference from the function _gpio_twl4030_probe() to the function
.devexit.text:_gpio_twl4030_remove()
The function __devinit _gpio_twl4030_probe() references a function
__devexit _gpio_twl4030_remove().
This is often seen when error handling in the init function uses
functionality in the exit path.
The fix is often to remove the __devexit annotation of
_gpio_twl4030_remove() so it may be used outside an exit section.

Provide a static debounce configuration mechanism for twl4030 GPIOs,
replacing the previous dynamic one. The single user of that mechanism was
for MMC card detect debouncing.
Boards can provide a bitmask saying which GPIOs to debounce (30 msec).
It's always enabled for pins with the MMC card-detect/VMMCx link active,
so most boards won't need to set the debounce mask.
This is a net code shrink, including runtime footprint.

This adds basic support for the GPIOs in the twl4030 power management
chip. That includes two open drain LED drivers, and the use of GPIO-0
(and GPIO-1) as MMC/SD card detect switches which can control whether
the VMMC1 (and VMMC2) regulators are active.
This version of the code has a debounce call that will probably be
replaced before long, when a more generic interface exists.
