Suman Anna 39879c7d96 ARM: dts: dra7xx-clocks: Source IPU1 functional clock from CORE DPLL
The IPU1 functional clock is actually the output of a mux clock,
ipu1_gfclk_mux. The mux clock is sourced by default from the
DPLL_ABE_X2_CLK, and this results in a rather odd clock frequency
(361 MHz) for the IPU1 functional clock on platforms where ABE_DPLL
is configured properly. Reconfigure the mux clock to be sourced from
CORE_IPU_ISS_BOOST_CLK (dpll_core_h22x2_ck), so that both the IPU1
and IPU2 are running from the same clock and clocked at the same
nominal frequency of 425 MHz.

This also ensures that IPU1 functional clock is always configured
properly and becomes independent of the state of the ABE DPLL on
all boards.
