gma tgl: Add support for allocating PLLs

This patch adds support for allocating both combo PHY PLLs and USB
Type-C PLLs for Tiger Lake.

Verified Combo PHY (HDMI, eDP) and Type-C (DP Alt mode) on
Google/delbin.

Squashed clean-ups:

gma tgl: Clean up the code for gfx plls

This patch improves code quality through various optimizations, such as
    replacing indexed array access with direct value access and simplifying
    variable declarations. It also simplifies function rewrites by using
    constructs like case-when instead of multiple range mappings or if else
    blocks. Additionally, the patch addresses minor typographical errors.
    These changes enhance the code's readability and maintainability
    without impacting functionality.

gma tgl: Rename DKL PLL to Dekel_Phy

This patch changes the name of a PLL "DKL" to "Dekel_Phy" to maintain
    consistency with the naming convention of other PHY PLLs
