Looks like some misunderstanding is here. This patch *only* removes
platform data for TWL603x
which were used to create TWL sub-devices like regulators, adc's,
watchdogs, etc.
Previously it was set up in twl_common.c by omap4_pmic_init(), which
was called from board files
with specific pmic config.
Since now in Linux kernel 3.13 OMAP4 non-DT boot is not supported and
all OMAP4 board files
have been removed omap4_pmic_init() is never called and all TWL603x
sub-devices are created
from device tree data.
