Introduce a config option for each QMP PHY driver now that the QMP PHY
mega-driver has been split up into different modules. This allows kernel
configurators to limit the binary size of the kernel by only compiling
in the QMP PHY driver that they need.

Leave the old config QCOM_QMP in place and make it into a menuconfig so
that 'make olddefconfig' continues to work. Furthermore, set the default
of the new Kconfig symbols to be QCOM_QMP so that the transition is
smooth.
