[PATCH 1/5] arm: mach-k3: j721e: Fix clk-data parenting for postdiv PLL clocks

From: Suman Anna <s-anna at ti.com>

The TI K3 Fractional PLLs use two programmable POSTDIV1 and POSTDIV2
divisors to generate the final FOUTPOSTDIV clock. These are in sequence
with POSTDIV2 following the POSTDIV1 clock. The current J721E clock data
has the POSTDIV2 clock as the parent for the POSTDIV1 clock, which is
opposite of the actual implementation. Fix the data by simply adjusting
the register bit-shifts.

The Main PLL1 POSTDIV clocks were also defined incorrectly using Main PLL0
register values, fix these as well.
