Drop codes that are not implemented and long obsolete: WIN_READ_LONG,
WIN_READ_LONG_ONCE, WIN_WRITE_LONG, WIN_WRITE_LONG_ONCE, WIN_FORMAT
(all obsolete since ATA4), WIN_ACKMEDIACHANGE, WIN_POSTBOOT,
WIN_PREBOOT (obsolete since ATA3), WIN_WRITE_SAME (obsolete since
ATA3, code reused for something else in ACS2), WIN_IDENTIFY_DMA
(obsolete since ATA4).
Drop codes that are not implemented and vendor-specific:
EXABYTE_ENABLE_NEST, DISABLE_SEAGATE.
Drop WIN_INIT, it isn't implemented, its value used to be reserved,
and is used for something else since ATA8.
CFA_IDLEIMMEDIATE isn't specific to CFATA. ACS-2 shows it as a
defined command in ATA-1, -2 and -3. Rename to WIN_IDLEIMMEDIATE2.
Mark vendor specific, retired, and obsolete codes.

ide: Update command code definitions as per ACS-2 Table B.2
Drop WIN_SRST, it has the same value as WIN_DEVICE_RESET.
Drop unused WIN_RESTORE, it has the same value as WIN_RECAL.
Drop codes that are not implemented and long obsolete: WIN_READ_LONG,
WIN_READ_LONG_ONCE, WIN_WRITE_LONG, WIN_WRITE_LONG_ONCE, WIN_FORMAT
(all obsolete since ATA4), WIN_ACKMEDIACHANGE, WIN_POSTBOOT,
WIN_PREBOOT (obsolete since ATA3), WIN_WRITE_SAME (obsolete since
ATA3, code reused for something else in ACS2), WIN_IDENTIFY_DMA
(obsolete since ATA4).
Drop codes that are not implemented and vendor-specific:
EXABYTE_ENABLE_NEST, DISABLE_SEAGATE.
Drop WIN_INIT, it isn't implemented, its value used to be reserved,
and is used for something else since ATA8.
CFA_IDLEIMMEDIATE isn't specific to CFATA. ACS-2 shows it as a
defined command in ATA-1, -2 and -3. Rename to WIN_IDLEIMMEDIATE2.
Mark vendor specific, retired, and obsolete codes.
