drivers: pinctrl: Add Qualcomm SDM630/660 TLMM driver
Add support for TLMM pin controller block (Top Level Mode Multiplexer) on SDM630/660 SoCs, with support for special pins. Correct pin configuration is required for working debug UART and eMMC/SD cards. SDM630 and SDM660 TLMM blocks are the same.
