powerpc/85xx: Fix signedness bug in cache-sram
sram_params.sram_size and sram_params.sram_offset were unsigned. If get_cache_sram_size() or get_cache_sram_offset() returns error code then it is not seen to the caller. Made sram_size and sram_offset signed. Signed-off-by: Vasiliy Kulikov <segooon@gmail.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
