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
into arguments for smc call. Consolidate the dispersed logic to convert
qcom_scm_desc into smc arguments inside qcom_scm_call_smccc.

Remove thin wrapper to qcom_scm_call_do_smccc because it doesn't do

Remove knowledge of arm_smccc_res struct from client wrappers so that
client wrappers only work QCOM SCM data structures. SCM calls may have
up to 3 arguments, so qcom_scm_call_smccc is responsible now for filling
those 3 arguments accordingly.

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.

Definitions throughout qcom_scm are loosely grouped and loosely ordered.
Sort all the functions/definitions by service ID/command ID to improve

Qcom's smmu-500 needs to toggle wait-for-safe sequence to

Few firmwares allow doing that through SCM interface.
