[ARM] 5080/1: touch PSSR_OTGPH only on pxa27x in ohci-pxa27x and pxa27x_udc

and include pxa2xx-regs.h as build fix since PSSR definitions
moved from pxa-regs.h into pxa2xx-regs.h.

Note: This change is temporary as pxa27x processor specific
code will be finally moved elsewhere (both drivers should
support pxa3xx, too).
