drm/msm/dsi/phy: Program clock inverters in correct register

Since SM8250 all downstream sources program clock inverters in
PLL_CLOCK_INVERTERS_1 register and leave the PLL_CLOCK_INVERTERS as
reset value (0x0).  The most recent Hardware Programming Guide for 3 nm,
4 nm, 5 nm and 7 nm PHYs also mention PLL_CLOCK_INVERTERS_1.
