This patch makes numerous miscellaneous code improvements to the QE library.
1. Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type()
(every caller of ucc_init_guemr() also calls ucc_set_type()). Modify all
callers of ucc_set_type() accordingly.
2. Remove the unused enum ucc_pram_initial_offset.
3. Refactor qe_setbrg(), also implement work-around for errata QE_General4.
4. Several printk() calls were missing the terminating \n.
5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where
appropriate.
6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed
with the wrong value.
7. Add the protocol type to struct us_info and updated ucc_slow_init() to
use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED.
8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx()
9. Add several macros in qe.h (mostly for slow UCC support, but also to
standardize some naming convention) and remove several unused macros.
10. Update ucc_geth.c to use the new macros.
11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol
to use when initializing the UCC in ucc_slow_init().
12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since
these are the real names of the registers.
13. Use the setbits, clrbits, and clrsetbits where appropriate.
14. Refactor ucc_set_qe_mux_rxtx().
15. Remove all instances of 'volatile'.
16. Simplify get_cmxucr_reg();
17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[].
18. Updated struct ucc_geth because struct ucc_fast is not padded any more.
