[U-Boot] [PATCH RFT] gpio: lpc32xx: Use priv data instead of platdata

[Axel Lin <axel.lin@ingics.com>]

Initially I found this driver has set priv_auto_alloc_size but it actually
never use dev->priv. The U_BOOT_DEVICE(lpc32xx_gpios) does not provide the
platdata and all fields in struct lpc32xx_gpio_platdata are set in probe.
It looks like the struct lpc32xx_gpio_platdata actually should be a priv
data. Thus this patch renames lpc32xx_gpio_platdata to lpc32xx_gpio_priv
and converts all dev_get_platdata() to dev_get_priv().

Hi Albert,
I don't have this h/w for testing, so only compile test.
I'd appreciate if you can review and test this patch.
Thanks,
Axel
