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, or to split the module up into one per PHY driver instead of one module for all the QMP PHY drivers. 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.
