Timur Tabi 6b0b594bb8 [POWERPC] qe: miscellaneous code improvements and fixes to the QE library 
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.
