[PATCH v2 4/7] USB: mos7720: rename DCR

While building with mn10300 it failed with:
error: expected identifier before '(' token
#define __SYSREG(ADDR, TYPE) (*(volatile TYPE *)(ADDR))
note: in expansion of macro '__SYSREG'
#define DCR __SYSREG(0xc0000030, u16) /* Debug control register */
mn10300 has a register named as DCR, so when this driver used an enum
named as DCR, build failed.
Just rename the DCR in the driver to parport_DCR.
