    arm: Fix parsecpu.awk for aliases [PR113030]
    
    So the problem here is the 2 functions check_cpu and check_arch use
    the wrong variable to check if an alias is valid for that cpu/arch.
    check_cpu uses cpu_optaliases instead of cpu_opt_alias. cpu_optaliases
    is an array of index'ed by the cpuname that contains all of the valid aliases
    for that cpu but cpu_opt_alias is an double index array which is index'ed
    by cpuname and the alias which provides what is the alias for that option.
    Similar thing happens for check_arch and arch_optaliases vs arch_optaliases.
    
    Tested by running:
    ```
    awk -f config/arm/parsecpu.awk -v cmd="chkarch armv7-a+simd" config/arm/arm-cpus.in
    awk -f config/arm/parsecpu.awk -v cmd="chkarch armv7-a+neon" config/arm/arm-cpus.in
    awk -f config/arm/parsecpu.awk -v cmd="chkarch armv7-a+neon-vfpv3" config/arm/arm-cpus.in
    ```
    And they don't return error back.

            * config/arm/parsecpu.awk (check_cpu): Use cpu_opt_alias
            instead of cpu_optaliases.
            (check_arch): Use arch_opt_alias instead of arch_optaliases.
