Rework (again) platform support for dual-role chipidea USB controller:
- include support for QCA9531
- use correct EHCI block size
- drop ar933x_usb_setup_ctrl_config() function
- simplify code after previous "register chipidea only in device mode"
change (fa22714181)
Reworked patch was tested on devices with below QCA WiSOCs (signal/GPIO
name with required bootstrap state for USB bus 0 in device mode):
- AR9331 (GPIO13 pull-down)
- AR9342 (RGMII_TXD1/ETXD1 pull-up)
- AR9344 (GPIO20 pull-up)
- QCA9531 (GPIO13 pull-up)
- QCA9558 (GPIO13 pull-up)
The only way to select device mode for bus 0 is to change SOC bootstrap
configuration which is sampled only once, at hard reset. Likely, other
models, like QCA9556 or AR9341, should also support dual-role USB mode
but they were not tested.

Only register the chipidea usb device if the strapping option indicates
device mode. If not, use the regular ehci platform driver.
Add qca955x device mode support, tested on 8devices Rambutan.

This add support for kernel 4.9 to the ar71xx target.
It was compile tested with the generic, NAND and mikrotik subtarget.
Multiple members of the community tested it on their boards and did not
report any major problem so far.
Especially the NAND part received some changes to adapt to the new
kernel APIs. The serial driver hack used for the Arduino Yun was not
ported because the kernel changed there a lot.
