media: sunxi: a83-mips-csi2: also select GENERIC_PHY

[ Upstream commit 82370261 ]

When selecting GENERIC_PHY_MIPI_DPHY, also select GENERIC_PHY to
prevent kconfig warnings:

WARNING: unmet direct dependencies detected for GENERIC_PHY_MIPI_DPHY
  Depends on [n]: GENERIC_PHY [=n]
  Selected by [y]:
  - VIDEO_SUN8I_A83T_MIPI_CSI2 [=y] && MEDIA_SUPPORT [=y] && MEDIA_PLATFORM_SUPPORT [=y] && MEDIA_PLATFORM_DRIVERS [=y] && V4L_PLATFORM_DRIVERS [=y] && VIDEO_DEV [=y] && (ARCH_SUNXI || COMPILE_TEST [=y]) && PM [=y] && COMMON_CLK [=y] && RESET_CONTROLLER [=y]

Fixes: 94d7fd96
