drm/i915/display: harden shifts in ICL_DPCLKA_CFGCR0_DDI_CLK_SEL macros
ICL_DPCLKA_CFGCR0 has a 2-bit DDI_CLK_SEL field per combo PHY, for
PHY_A..PHY_D only. Any other phy value (PHY_NONE, TypeC/SNPS PHYs) is
not valid here.
This is not a problem with the current implementation, because phy is
always valid when these macros are called, but it's more robust to
cast to unsigned so the shift is always well-defined.
