Legacy platform_data removal for omaps for v4.10 merge window. 

We've dropped the last legacy boot board-*.c files for mach-omap2
 for v4.9 so now we can start removing the unused platform_data.
 
 All of the below has been unused since v4.9 merge window:
 
 - Drop legacy pmic init code
 
 - Apply seq_puts() fixes for legacy mux code, then drop it
 
 - Drop legacy serial init
 
 - Drop legacy i2c init
 
 - Drop legacy PM init
 
 - Drop legacy twl4030 platform init
 
 - Drop legacy USB host init
 
 - Drop legacy muxing for tusb6010, n8x0 is still using it's
   platform init via pdata-quirks.c
 
 - Drop legacy musb init
 
 - Drop hwmod related legacy mux code
 
 - Drop legacy hwmod data for omap3
 
 - Drop legacy smsc911x and smc91x init
 
 - Drop legacy board flash init
 
 - Drop legacy ads7846 init
 
 - Drop legacy sdram timings

help
Pin multiplexing support for OMAP boards. If your bootloader
sets the multiplexing correctly, say N. Otherwise, or if unsure,
say Y.
config OMAP_MUX_DEBUG
bool "Multiplexing debug output"
depends on OMAP_MUX
help
Makes the multiplexing functions print out a lot of debug info.
This is useful if you want to find out the correct values of the
multiplexing registers.
config OMAP_MUX_WARNINGS
bool "Warn about pins the bootloader didn't set up"
depends on OMAP_MUX

help
Choose Y here to warn whenever driver initialization logic needs
to change the pin multiplexing setup. When there are no warnings
printed, it's safe to deselect OMAP_MUX for your product.
