drive_cmd_intr() is used by both REQ_TYPE_ATA_CMD and REQ_TYPE_ATA_TASK
but commands using PIO-in protocol are valid only for REQ_TYPE_ATA_CMD
(&args[4] in case of REQ_TYPE_ATA_TASK points to a value for IDE_LCYL_REG
register instead of the data buffer). This fix allows REQ_TYPE_ATA_TASK
commands to use non-zero values for IDE_SECTOR_REG (args[3]).

In piix.c (and in ata_piix.c) are already included some patches to skip the
cable check on some laptops and to enable UDMA > 33 modes, but I've noticed
than theese doesn't work on my Acer Aspire 5602WLMi (maybe exist more
versions of this laptop). With this simple patch I can set transfer mode
to UDMA100.

It turns out that const and __{dev}initdata cannot be mixed currently
and that generic IDE PCI host driver is also affected by the same issue:

This patch workarounds the problem in a bit hackish way but without
removing const from generic_chipsets[] (it adds const to __setup() so
__setup_str_ide_generic_all becomes const).
Now all __{dev}initdata data in generic IDE PCI host driver are read-only
so it builds again (driver's .init.data section gets marked as READONLY).

This patch workarounds the problem by making static struct hpt_info instances
const. Now all __devinitdata data in hpt366 host driver are read-only so it
builds again (driver's .init.data section gets marked as READONLY).

It turns out that const and __{dev}initdata cannot be mixed currently.
This patch workarounds the problem by removing __devinitdata tag from 'primary'
variable (which makes 'primary' to be moved from .init.data to .bss section).
Now all __devinitdata data in cy82c693 host driver are read-only so it builds
again (driver's .init.data section gets marked as READONLY).
While at it:
* Move 'primary' variable to its only user, init_iops_cy82c693().
* Bump driver version.
