usb: gadget: Add snapshot of ChipIdea MSM driver

Add the snapshot ChipIdea-based UDC drivers for MSM chipsets for
USB. This snapshot is taken from msm-3.10 'commit f62f95b715a5
("Merge "dwc3-msm: Turn on 1.8V LDO before turning on 3.3V LDO"")'.

Also remove ACA and SRP/HNP related code which is no longer used

Changes were also made to allow successful compiliation:
 - Omitted qcom/usb_trace.h and removed references to ebi_erp
 - converted usleep() to usleep_range()
