qcom-llcc-pmu: update the version enum

Update the enum values used to differentiate the hardware
changes, because in the probe function after parsing the DT
the version value is checked with zero, and the LLCC_PMU_VER1
enum value is zero according enum definitation, if the DT entry
passed as LLCC_PMU_VER1 the check will fail and llcc-pmu driver is
not registered.

update enum LLCC_PMU_VER1 to value 1.
