PATA fixes

Hi,

I've been going through PATA drivers for the last few days to make sure that we offer similar level of hardware support in the new PATA drivers as with the old IDE subsystem and the following patchset is the end result of said audit.

Inside:

- many bugfixes

( ata_piix, pata_artop, pata_atiixp, pata_efar, pata_cmd64x,

    pata_hpt3x3, pata_it8213, pata_legacy, pata_ns87415, pata_sis,
    pata_radisys, pata_rz1000 & pata_via )

- add Power Management support for more controllers

( pata_artop, pata_pdc2027x, pata_sl82c105 )

- add 32-bit PIO support for more controllers

( pata_artop, pata_atiixp, pata_efar, pata_cmd64x, pata_cs5520,

    pata_cs5530, pata_cs5535, pata_cypress, pata_hpt366, pata_hpt37x,
    pata_hpt3x2n, pata_it8213, pata_it821x, pata_jmicron, pata_ns87415,
    pata_opti, pata_pdc2027x, pata_pdc202xx_old, pata_rz1000,
    pata_sc1200, pata_scc, pata_sch, pata_serverworks, pata_sl82c105,
    pata_sis, pata_triflex & pata_via )

- fix QDI65x0 support in pata_legacy driver so pata_qdi driver can be finally removed

- remove pata_qdi and pata_winbond drivers resulting in 600 LOC gone

(affected hardware is fully supported by pata_legacy driver now)

- unify code for programming PIO and MWDMA timings for 'PIIX-like' controllers resulting in 200 LOC gone

( ata_piix, pata_efar, pata_it8213, pata_oldpiix, pata_radisys &
pata_rdc )

- add ->init_host method for abstracting host specific controller initialization and then use it to cleanup Power Managment code resulting in over 100 LOC gone

( pata_ali, pata_amd, pata_artop, pata_cmd640, pata_cmd64x,

    pata_cs5530, pata_hpt366, pata_hpt3x3, pata_it821x, pata_ninja32,
    pata_ns87415, pata_pdc2027x & sata_sil )

- misc fixes and cleanups
