In LUCID EVO PLL CAL_L_VAL and L_VAL bitfields are part of single
PLL_L_VAL register. Update for L_VAL bitfield values in PLL_L_VAL
register using regmap_write() API in __alpha_pll_trion_set_rate
callback will override LUCID EVO PLL initial configuration related
to PLL_CAL_L_VAL bit fields in PLL_L_VAL register.
Observed random PLL lock failures during PLL enable due to such
override in PLL calibration value. Use regmap_update_bits() with
L_VAL bitfield mask instead of regmap_write() API to update only
PLL_L_VAL bitfields in __alpha_pll_trion_set_rate callback.
