soc: amlogic: meson-clk-measure: protect measure with a mutex
In order to protect clock measuring when multiple process asks for
a measure, protect the main measure function with mutexes.

soc: amlogic: Add Meson Clock Measure driver
The Amlogic Meson SoCs embeds a clock measurer IP to measure the internal
clock paths frequencies.
The precision is determined by stepping into the duration until the counter
overflows.
The debugfs slows a pretty summary and each clock can be measured
individually aswell.
