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)

USB: move many drivers to use DEVICE_ATTR_RW 2018-01-24T07:49:51+00:00 Greg Kroah-Hartman gregkh@linuxfoundation.org 2018-01-23T10:24:05+00:00 ed5bd7a47fd77166860e39f857ae8e3fe25c836c Instead of "open coding" a DEVICE_ATTR() define, use the DEVICE_ATTR_RW() macro instead, which does everything properly instead. This does require a few static functions to be renamed to work properly, but thanks to a script from Joe Perches, this was easily done.

Due to there is a hardware bug with the LINE STATE wakeup mode on mt8173 which causes wakeup failure by low speed devices, and also because IP SLEEP mode can cover all functions of LINE STATE mode, it is unused in fact, and will not support it later, so remove it at the same time.
