Current code never allowed the page pool to actualy fill in anyway.
This fix it, so that we only start freeing page from the pool when
we go over the pool size.

Changed since v1:
  - Move the page batching optimization to its separate patch.

Changed since v2:
  - Do not remove code part of the batching optimization with
    this patch.
  - Better commit message.

In case the gpiochip doesn't have the .dev field set, as is the case

xgpio_save_regs() is used in this driver to setup the initial
values of the registers in the hardware.

The relevant registers at that time are:
0x0 -> channel 0 data (32 bits, one for each GPIO on this channel).
0x4 -> channel 0 tri, controls in/out status for each GPIO of this channel.
0x8 -> channel 1 data
0xC -> channel 1 tri

gpio-xilinx.c defines these:
XGPIO_DATA_OFFSET   (0x0)
XGPIO_TRI_OFFSET    (0x4)
XGPIO_CHANNEL_OFFSET	0x8

Before this patch, the "data" register value of channel 1 was written
at 0x4 intead of 0x8 (overwriting the channel 0 "tri" register),
and the "tri" register value for channel 1 was written at 0x8 instead of 0xC.

If a failure occurs during probe, brcmstb_gpio_remove() is called. In
remove, we call platform_get_drvdata(), but at the time of failure in
the probe the driver data hadn't yet been set which leads to a NULL
ptr dereference in the remove's list_for_each.  Call
platform_set_drvdata() and set up list head right after allocating the
priv struct to both avoid the null pointer dereference that could
occur today.  To guard against potential future changes, check for
null pointer in remove.
