ARM: uniphier: drop PH1- prefix from CONFIG options and file names
The current CONFIG names like "CONFIG_ARCH_UNIPHIER_PH1_PRO4" is too long. It would not hurt to drop "PH1_" because "UNIPHIER_" already well specifies the SoC family. Also, rename files for consistency. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
