commit ec897569ad7dbc6d595873a487c3fac23f463f76 upstream.

Move the Kconfig symbols USB_UHCI_BIG_ENDIAN_MMIO and
USB_UHCI_BIG_ENDIAN_DESC out of drivers/usb/host/Kconfig, which is
conditional upon USB && USB_SUPPORT, so that it can be freely selected
by platform Kconfig symbols in architecture code.

For example once the MIPS_GENERIC platform selects are fixed in commit
2e6522c56552 ("MIPS: Fix typo BIG_ENDIAN to CPU_BIG_ENDIAN"), the MIPS
32r6_defconfig warns like so:

warning: (MIPS_GENERIC) selects USB_UHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies (USB_SUPPORT && USB)
warning: (MIPS_GENERIC) selects USB_UHCI_BIG_ENDIAN_DESC which has unmet direct dependencies (USB_SUPPORT && USB)

Quoting Hans: If we return 1 from our post_reset handler, then our disconnect handler will be called immediately afterwards. Since pre_reset blocks all scsi requests our disconnect handler will then hang in the scsi_remove_host call. This is esp. bad because our disconnect handler hanging for ever also stops the USB subsys from enumerating any new USB devices, causes commands like lsusb to hang, etc. In practice this happens when unplugging some uas devices because the hub code may see the device as needing a warm-reset and calls usb_reset_device before seeing the disconnect. In this case uas_configure_endpoints fails with -ENODEV. We do not want to print an error for this, so this commit also silences the shost_printk for -ENODEV.
