[PATCH] arm: bump amount of PMU counters to pass SBSA ACS

[Marcin Juszkiewicz]

Arm BSA (Base System Architecture) specification says:

B_PE_09: PEs must implement the FEAT_PMUv3p1 extension, and the base
system must expose a minimum of four programmable PMU counters to the
operating system.

B_PE_21: The base system must expose a minimum of two programmable PMU
counters to a hypervisor.

It is then repeated in SBSA (Server Base System Architecture)
specification in level 3 requirements:

Each PE must implement a minimum of six programmable PMU counters.

So let make QEMU provide those 6 PMU counters.

SBSA-ACS says now:

  12 : Check number of PMU counters      : Result:  PASS
