ARM: dts: msm: Update Reference Clock to clk8_a4 for Kera UFS 2.x

Browse Source 
The Kera UFS 2.x requires a reference clock of 19.2MHz. Currently,
the reference clock provided by the DTSI node RPMH_LN_BB_CLK3
returns clk_get_rate() as 38.4MHz.

To address this, the handler is updated to use clk8_a4, ensuring the
clock rate is set to 19.2MHz.
