New subject: [U-Boot] [PATCH 2/9] ARM: uniphier: update DRAM init code for LD20 SoC (2nd)

- Do not reference CONFIG_DDR_FREQ; now the DDR frequency is passed from the uniphier_board_data structure - Constify parameter arrays - Tidy up cluttered macros - Lots of code cleanups - Lots of coding style fixes
