[PATCH 05/10] [v2] mips: select legacy gpiolib interfaces where used

From: Arnd Bergmann <[email protected]>

A few old machines have not been converted away from the old-style
gpiolib interfaces. Make these select the new CONFIG_GPIOLIB_LEGACY
symbol so the code still works where it is needed but can be left
out otherwise.

This is the list of all gpio_request() calls in mips:

  arch/mips/alchemy/devboards/db1000.c:           gpio_request(19, "sd0_cd");
  arch/mips/alchemy/devboards/db1000.c:           gpio_request(20, "sd1_cd");
  arch/mips/alchemy/devboards/db1200.c:   gpio_request(215, "otg-vbus");
  arch/mips/bcm47xx/workarounds.c:        err = gpio_request_one(usb_power, GPIOF_OUT_INIT_HIGH, "usb_power");
  arch/mips/bcm63xx/boards/board_bcm963xx.c:              gpio_request_one(board.ephy_reset_gpio,
  arch/mips/txx9/rbtx4927/setup.c:        gpio_request(15, "sio-dtr");

Most of these should be easy enough to change to modern gpio descriptors
or remove if they are no longer in use.

v2: no changes. There was no discussion on this, but the patch
    has so far not made it into the linux-mips tree, so I'm including
    it for completeness.
