ARM: davinci: add platform hook to fetch the SRAM pool
Adds sram_get_gen_pool() which allows platform code to get the machine's SRAM gen_pool. The gen_pool may be passed in platform data for driver genalloc use. Signed-off-by: Matt Porter <mporter@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
