DA830: fix SPI1 base address
Commit 54ce6883d29630ff334bee4256a25e3f8719a181 (davinci: da8xx: add spi resources and registration routine) wrongly assumed that SPI1 is mapped at the same address on DA830/OMAP-L137 and DA850/OMAP-L138; actually, the base address was valid only for the latter SoC. Teach the code to pass the correct SPI1 memory resource for both SoCs... Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
