Subject: [PATCH AUTOSEL for 4.9 10/50] clk: samsung: exynos5433: Add IDs for
 PHYCLK_MIPIDPHY0_* clocks

From: Marek Szyprowski <m.szyprowski@...sung.com>

[ Upstream commit 5ccb58968bf7f46dbd128df88f71838a5a9750b8 ]

Add missing identifiers for phyclk_mipidphy0_bitclkdiv8_phy and
phyclk_mipidphy0_rxclkesc0_phy clocks. Access to those clocks is needed
to setup initial clock configuration for display subsystem in device tree
in order to avoid dependency on the configuration left by the bootloader.
