drivers: soc: qcom: Add sdmmagpie SoC llcc driver

Add LLCC driver which contains the configuration data required to
program the LLCC on SDMMAGPIE SoC. The configration data controls the
behavior of LLCC by setting priority, size, how the ways are allocated
when clients use the LLCC and so on. Platform specific driver calls into
the common LLCC driver to program this configuration.
