Convert the DBSC QoS setting function to a simple table of register-value
pairs and pass it to common rcar_qos_dbsc_setting() to write those values
to matching registers.

The DBSC_SCFCTST2 is always written with the same value, no matter
what the MD pin value is, drop the entire check and just write the
register with the one and only possible value.

Move the DBSC write enabling and disabling to dbsc_setting() function,
to make it local, instead of having it all over the code.

Convert the mstat table from a complex structure to simple sequence
of uint64_t values, since the structure described just that and the
loop can operate over incrementing sequence of addresses just fine.

Pull out the mstat fix array into separate file, to align the structure
of the driver with the other SoCs. No functional change.
