refactor(cpus): convert Cortex-A35 to use the errata framework

This involves replacing:
 * the reset_func with the standard cpu_reset_func_{start,end} to apply
   errata automatically
 * the <cpu>_errata_report with the errata_report_shim to report errata
   automatically
...and for each erratum:
 * the prologue with the workaround_<type>_start to do the checks and
   framework registration automatically
 * the epilogue with the workaround_<type>_end
 * the checker function with the check_erratum_<type> to make it more
   descriptive

It is important to note that the errata workaround and checking
sequences remain unchanged and preserve their git blame. Testing was
conducted by:

 * Manual comparison of disassembly of converted functions with non-
   converted functions.

	aarch64-none-elf-objdump -D <TF-A with
	conversion>/build/../release/bl31/bl31.elf
     	vs
	aarch64-none-elf-objdump -D <TF-A with
	clean repo>/build/fvp/release/bl31/bl31.elf

 * Build for release with all errata flags enabled and ensure the
   changes were identical.
	CROSS_COMPILE=aarch64-none-elf- make PLAT=fvp \
	DEBUG=0 HW_ASSISTED_COHERENCY=0 \
	BL33=<tf-a-tests>/build/fvp/debug/tftf.bin \
	all fip ERRATA_A35_855472=1

 * Build for debug with all errata enabled and step through ArmDS
   at reset to ensure all functions are entered.
