Errata printing is done directly via generic_errata_report.
This commit removes the unused \_cpu\()_errata_report
functions for all cores, and removes errata_func from cpu_ops.

Cortex-A720 erratum 2926083 is a Cat B erratum that is present
in revisions r0p0, r0p1 and is fixed in r0p2. The errata is only
present when SPE (Statistical Profiling Extension) is implemented
and enabled.
The workaround is to set bits[58:57] of the CPUACTLR_EL1 to 'b11
when SPE is "implemented and enabled".

Cortex-A720 erratum 2940794 is a Cat B erratum that is present
in revision r0p0, r0p1 and is fixed in r0p2.
The workaround is to set bit[37] of the CPUACTLR2_EL1 to 1.

Adapt to use errata frame-work cpu macro helpers for following cpus:
- cortex-a520
- cortex-a720
- cortex-x4
- cortex-chaberton
- cortex-blackhawk
- Use sysreg_bit_set helper macro for enabling of any system register
bit field.
- Use errata_report_shim macro for reporting errata.
- Use cpu_reset_func_start/end helpers for adding cpu reset functions.
Testing:
- Manual comparison of disassembly with and without conversion.
- Using the test script in gerrit - 19136
- Building with erratas and stepping through from ArmDS and running tftf.
