dcd/ch58x: preserve the DEV_ADDR general-purpose bit on SET_ADDRESS
dcd_edpt0_status_complete() wrote the full SET_ADDRESS wValue into R8_USB_DEV_AD,
clobbering bit 7, which on CH58x is a user general-purpose flag (only bits [6:0]
are the device address). Mask to 7 bits and preserve bit 7, matching the removed
dcd_ch58x_usbfs.c. CH58x-scoped; other parts keep the full write.
