Teik Heng Chong 9c9454ac2e usb: dwc2: Fix the write to W1C fields in HPRT register 
Fix the write to the HPRT register which treat W1C fields
as if they were mere RW. This leads to unintended clearing of such fields

This bug was found during the testing on Simics model. Referring to
specification DesignWare Cores USB 2.0 Hi-Speed On-The-Go (OTG)
Databook (3.30a)"5.3.4.8 Host Port Control and Status Register (HPRT)", the
HPRT.PrtPwr is cleared by this mistake. In the Linux driver (contrary to
U-Boot), HPRT is always read using dwc2_read_hprt0 helper function which
clears W1C bits. So after write back those bits are zeroes.
