ARM: at91: fix at91_suspend_entering_slow_clock link error
When CONFIG_ARCH_AT91 is enabled, but none of the specific SoC support is in use, some at91 specific drivers fail to link: drivers/tty/serial/atmel_serial.o: In function `atmel_serial_suspend': atmel_serial.c:(.text.atmel_serial_suspend+0x1e): undefined reference to `at91_suspend_entering_slow_clock' drivers/usb/host/ohci-at91.o: In function `ohci_hcd_at91_drv_suspend': ohci-at91.c:(.text.ohci_hcd_at91_drv_suspend+0x12): undefined reference to `at91_suspend_entering_slow_clock' drivers/usb/gadget/udc/at91_udc.o: In function `at91udc_suspend': at91_udc.c:(.text.at91udc_suspend+0x26): undefined reference to `at91_suspend_entering_slow_clock' This changes the at91_suspend_entering_slow_clock hack once more, adding an alternative inline implementation that is used exactly in those cases that don't provide the normal implementation.
