sh_eth: rename EESIPR bits
Since the commit b0ca2a21f769 ("sh_eth: Add support of SH7763 to sh_eth") the *enum* declaring the EESIPR bits (interrupt mask) went out of sync with the *enum* declaring the EESR bits (interrupt status) WRT bit naming and formatting. I'd like to restore the consistency by using EESIPR as the bit name prefix, renaming the *enum* to EESIPR_BIT, and (finally) renaming the bits according to the available Renesas SH77{34|63} manuals; additionally, reconstruct couple names using the EESR bit declaration above...
