bus: mhi: pci_generic: Introduce Foxconn T99W175 support 

Add support for T99W175 modems, this modem series is based on SDX55
qcom chip. The modem is mainly based on MBIM protocol for both the
data and control path.

This patch adds support for below modems:

 - T99W175(based on sdx55), Both for eSIM and Non-eSIM
 - DW5930e(based on sdx55), With eSIM, It's also T99W175
 - DW5930e(based on sdx55), Non-eSIM, It's also T99W175

This patch was tested with Ubuntu 20.04 X86_64 PC as host
