Remove unused devclass argument to DRIVER_MODULE

• If __FreeBSD_version >= 1400058 remove unused devclass argument to DRIVER_MODULE
• Add MODULE_PNP_INFO() to rtsx
• More tweak for RTS5260 and add a BUGS entry in rtsx.4

Add model RTS5260 and update rtsx_resume()

• Add model RTS5260
• Add rtsx_init() in rtsx_resume() to solve issue on THINKPAD x250

Call taskqueue sooner, adjust some DELAY(), add inversion heuristic

• Some configuration (e.g. HP EliteBook 840 G3) have a dummy plastic in the card reader
  which is detected as a valid SD card. This induce long timeout at boot time.
  I introduce a reduce timeout (1 second) during the setup phase to alleviate this problem.
  See bug 255130.
• Some configuration crash at boot if rtsx is defined in the kernel config.
  See this mail.
  At boot time, without a card inserted, the driver found that a card is present and just
  after that a "spontaneous" interrupt is generated showing that no card is present.
  To solve this I set the DELAY() to one quarter of a second before checking the card
  presence during driver attach.
• As advised by Adrian Chadd I setup taskqueue and dma sooner during the driver attach.
• I add a heuristic to try to detect configuration needing inversion.

The driver version commited to FreeBSD current

The MMCCAM version has bee added.

• To enable version for a kernel with MMCCAM:

make -D RTSX_CAM

Correct compilation fail on CURRENT

• add sysctl entries
• add reset to try to correct card detection when reboot from Windows.

The driver seems to be ready

• Replace msleep() - wakeup() by callout_reset() - callout_stop().
• set timeout to 10 secs.

First release candidate

To solve timeout during card insert and long sequence of writes:

• modify rtsx_set_sd_clock()
• implement rtsx_mmcbr_tune()
• modify hardware initialization for RTS5229.

Some more tweaks for RTS5227 and RTS522A

• For RTS5227 and RTS522A add fill driving in rtsx_mmcbr_switch_vccq()
• Add a RTSX_CLR in optimize phy for RTS5227
• Remove a RTSX_SET found in OpenBSD but not in Linux

Add vendor setting and update timing

• f_min = 250KHz and f_max = 208MHz
• add vendor settings
• add timing update to mmcbr_update_ios()
• add suspend/resume
• better error detection and error code

Add more tweaks for RTS5227

Return better error code (only MMC_ERR_*)
