dcd_da146xx: Remove registers pointer from xfer_ctl_t

Note: this commit does not change any logic.

xfer_ctl_t structure keeps all dynamic data connected with transfer.
It used to have pointer to register set that was constant and was there
for convenience only.
Removing register pointer from structure makes cleanup easier as whole
structure can be erased with memset like function.

In many cases functions were using local variable regs and xfer->regs which
were same, that could be confusing so this part is unified.

Few macros were added for easy conversion between epnum, xfer, and regs.
