soc: qcom: smd: Remove standalone driver

Browse Source 
Remove the standalone SMD implementation as we have transitioned the
client drivers to use the RPMSG based one.

Also remove all dependencies on QCOM_SMD from Kconfig files, in order to
keep them selectable in the absence of the removed symbol.
