Convert TWL6040 CODEC driver into a TWL6040 MFD child, it implies
that MFD-level operations like register accesses, clock setting
and power management are done through MFD APIs, not directly by
CODEC driver anymore. To avoid conflicts with the other MFD child,
vibrator registers are skipped in CODEC driver.

TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.

TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.

This driver is based on TWL4030 and WM8350 MFD drivers.

omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and
'dma_channel' are never referenced by the NAND driver, yet various
board files are initializing those fields. This is both incorrect and
confusing, so remove them. This allows to get rid of a global
variable in gpmc-nand.c.

This also corrects an issue where some boards are trying to pass NAND
16bit flag through .options, but the driver is using .devsize instead
and ignoring .options.

Finally, .dev_ready is treated as a flag by the driver, so make it bool
instead of a function pointer.

This means that we can initialize the sys_timer with the .timer
entries alone.

Note that for now we just set stubs for the various sys_timer entries
