[PATCHSET] sata_sil24: fixes, errata workaround and reset updates, take 2

[Tejun Heo <htejun@gmail.com>]

Hello, Jeff and Carlos.

This is the second take of sata_sil24-fixes-errata-workaround-and-
reset-updates patchset.  Changes from the last take[1] are...

* sil24_poll_register() is replaced by ata_wait_register()
* comment update as suggested by Jeff
* better constants
* byteorder fix and 64bit patches are pushed backward, as they're
  untested.
* hardreset routine updated to unconditionally wait 100ms after reset
* new patch #11 removes hardresetting in sil24_init_one() as it's
  already done during host reset and even if the port is in a funky
  state, we have hardreset to back us up.

This patchset contains 13 patches.

#01	prep
#02-06	fixes, updates, errata workaround
#07-09	update softreset
#10-11	update hardreset
#12-13	untested fixes

This patchset is against

  upstream[2]
  + libata-reset-updates patchset (3 patches) [3]
  + implement-and-use-ata_wait_register patchset [4]

After these updates, sil24 is ready for new EN and NCQ.  In my repo,
sil24 is working fine with both new EH and NCQ.

Thanks.
