board: phytec: common: Introduce CONFIG_PHYTEC_K3_DDR_PATCH

Introduce CONFIG_PHYTEC_K3_DDR_PATCH to make DDR timing patch code
optional for PHYTEC K3 boards. This allows better control over which
boards receive DDR timing patches, rather than compiling the code for
all boards with K3_DDRSS enabled.

Also enable the feature by default for PHYCORE_AM62X_R5.
