[U-Boot] [PATCH] ddr: altera: Drop custom dram_bank_mmu_setup() on Arria10

This function was never used in SPL and the default implementation of
dram_bank_mmu_setup() does the same thing. The only difference is the
part which configures OCRAM as cachable, which doesn't really work as
it covers more than the OCRAM.
