perf: hisi: Add support for HiSilicon SoC L3C PMU driver
This patch adds support for L3C PMU driver in HiSilicon SoC chip, Each
L3C has own control, counter and interrupt registers and is an separate
PMU. For each L3C PMU, it has 8-programable counters and each counter
is free-running. Interrupt is supported to handle counter (48-bits)
overflow.
