ARM: uniphier: split ProXstream2 board data and change DDR frequency
The DDR3 memory chips on ProXstream2 boards support up to 2133 MHz, while only up to 1866MHz on PH1-LD6b boards. Split the board data structure and change the DDR frequency of ProXstream2 boards to 2133 MHz. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
