ASoC: ti: j721e-evm: Fix clock configuration for ti,j7200-cpb-audio compatible

[ Upstream commit 45ff65e30deb919604e68faed156ad96ce7474d9 ]

For 'ti,j7200-cpb-audio' compatible, there is support for only one PLL for
48k. For 11025, 22050, 44100 and 88200 sampling rates, due to absence of
J721E_CLK_PARENT_44100, we get EINVAL while running any audio application.
Add support for these rates by using the 48k parent clock and adjusting
the clock for these rates later in j721e_configure_refclk.

Fixes: 6748d0559059 ("ASoC: ti: Add custom machine driver for j721e EVM (CPB and IVI)")
