tm5600/6000/6010 requires a large config table for video standards. Better to
move this to their own file.
Also added register settings for tm6010 (needs testing.

if a transfer buffer allocation fails, the last allocated urb is leaked
(it hasn't been stored in dev->urb[] yet so tm6000_uninit_isoc misses
it). The patch also includes a small typo fix.
Thanks to Florin Malita <fmalita@gmail.com> for pointing this.

Previously, there were no sync between video buffer filling and received
URBs. So, the presented image were a mix of frame and frame-1. Now, a
filled buffer should contain only data for that frame.
allocates a maximum of 64 KB per each URB area. This fixed two bugs:
- Sometimes, there were no available continuos block of about 1 MB;
- Image weren't not properly updated, since parts of the URBs aren't
updated.

Adds a driver for Trident TV Master tm5600/tm6000 chips.
Those USB devices are usually found with a Xceive xc2028/xc3028
tuner, although the firmware seems to be modified to work with
those chips on some older devices.

ATA_FLAG_DISABLED is only used by drivers which don't use
->error_handler framework and is largely broken. Its only meaningful
function is to make irq handlers skip processing if the flag is set,
which is largely useless and even harmful as it makes those ports more
likely to cause IRQ storms.
Kill ATA_FLAG_DISABLED and makes the callers disable attached devices
instead. ata_port_probe() and ata_port_disable() which manipulate the
flag are also killed.
This simplifies condition check in IRQ handlers. While updating IRQ
handlers, remove ap NULL check as libata guarantees consecutive port
allocation (unoccupied ports are initialized with dummies) and
long-obsolete ATA_QCFLAG_ACTIVE check (checked by ata_qc_from_tag()).

Use a 32-bit popcnt instruction for __arch_hweight32(), even on
x86-64. Even though the input register will *usually* be
zero-extended due to the standard operation of the hardware, it isn't
necessarily so if the input value was the result of truncating a
64-bit operation.
Note: the POPCNT32 variant used on x86-64 has a technically
unnecessary REX prefix to make it five bytes long, the same as a CALL
instruction, therefore avoiding an unnecessary NOP.
