Subject: [PATCH 5.19 463/717] clk: qcom: gcc-sm6115: Override default Alpha PLL regs

[ Upstream commit 068a0605ef5a6b430e7278c169bfcd25b680b28f ]

The DEFAULT and BRAMMO PLL offsets are non-standard in downstream, but
currently only BRAMMO ones are overridden. Override DEFAULT ones too.

A very similar thing is happening in gcc-qcm2290 driver.
