Enable legacy calling convention in qcom_scm-64. Add enum to represent
current calling convention being used. Update is_call_available to use
legacy function numbers when using legacy convention.

Copy/paste legacy SCM driver into qcom_scm-64 with the following notes:
- Renamed qcom_scm_call in qcom_scm-32 to qcom_scm_call_legacy in the
copy.
- Renamed qcom_scm_call_atomic in qcom_scm 32 to
qcom_scm_call_atomic_legacy in the copy.
- Rename __qcom_scm_call_smccc to qcom_scm_call_smccc.
- Filled in implementations set_cold_boot_addr, set_warm_boot_addr, and
cpu_power_down from qcom_scm-32.c.
- set_dload_mode, io_writel, io_readl now use atomic variants as in
qcom_scm-32.

Downstream SCM driver legacy atomic calling convention supports up to 5

- Move SMCCC register filling to qcom_scm_call so that qcom_scm_call_do
only needs to concern itself with retry mechanism.
- Use arm_smccc_args struct in atomic variants as well.

Improve the calling convention detection to use qcom_scm_call_atomic
and not blindly assume 32-bit mode if the checks fails.
__qcom_scm_is_call_available() cannot be used directly here as we want
an atomic variant of is_call_available(). This is also a necessary
requirement later when merging in legacy convention.

qcom_scm_call_smccc should be responsible for converting qcom_scm_desc

Remove knowledge of arm_smccc_res struct from client wrappers so that
client wrappers only work QCOM SCM data structures. SCM calls may have

Service, command, and owner IDs are all part of qcom_scm_desc struct and
have no special reason to be a function argument (or hard-coded in the
case of owner). Moving them to be part of qcom_scm_desc struct improves
readability.
