[MIPS] rbtx4938: Convert SPI codes to use generic SPI drivers
Use rtc-rs5c348 and at25 spi protocol driver and spi_txx9 spi controller driver instead of platform dependent codes. This patch also removes dependencies to old RTC interfaces such as rtc_mips_get_time, etc. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
