firmware: qcom_scm: Rename -64 -> -smc, remove -32
- Rename qcom_scm-64.c to qcom_scm-smc as it supports SMC-based calling conventions for 32 and 64-bit targets - Remove qcom_scm-32.c as it has been superceded by qcom_scm-smc.c - Update Kconfig to select QCOM_SCM_TRANSPORT_SMC on ARM and ARM64 targets Change-Id: Iae94a73e0c7cefb9a253230212d01f6126cd0c15 Signed-off-by: Elliot Berman <eberman@codeaurora.org>
