Add gpmc hwmod and associated interconnect data
HWMOD_INIT_NO_RESET can be removed once kernel is updated to
configure GPMC for all peripherals. Currently many depend on
bootloader, this facility will be removed.
(feature-removal-schedule.txt will get updated in upcoming
gpmc series).
No reset is also required for smooth migration to gpmc driver;
approach being taken is to hold old interface until boards are
converted to use driver interface one-by-one. Till that time,
this flag is a must as old interface rely on bootloader
