firmware: qcom_scm: Apply consistent naming scheme to command IDs

Browse source 
Create a consistent naming scheme for command IDs. The scheme is
QCOM_SCM_##svc_##cmd. Remove unused macros QCOM_SCM_FLAG_HLOS,
QCOM_SCM_FLAG_COLDBOOT_MC, QCOM_SCM_FLAG_WARMBOOT_MC,
QCOM_SCM_CMD_CORE_HOTPLUGGED, and QCOM_SCM_BOOT_ADDR_MC.
