The code in pinctrl-imx.c only works correctly if in the
imx_pinctrl_soc_info passed to imx_pinctrl_probe we have:
info->pins[i].number = i
conf_reg(info->pins[i]) = 4 * i
(which conf_reg(pin) being the offset of the pin's configuration
register).
When the imx25 specific part was introduced in b4a87c9b966f ("pinctrl:
pinctrl-imx: add imx25 pinctrl driver") we had:
info->pins[i].number = i + 1
conf_reg(info->pins[i]) = 4 * i
. Commit 34027ca2bbc6 ("pinctrl: imx25: fix numbering for pins") tried
to fix that but made the situation:
info->pins[i-1].number = i
conf_reg(info->pins[i-1]) = 4 * i
which is hardly better but fixed the error seen back then.
So insert another reserved entry in the array to finally yield:
info->pins[i].number = i
conf_reg(info->pins[i]) = 4 * i

The pin id for a given tuple listed in a fsl,pins property is calculated
by dividing the first entry (which is also a register offset) by 4.
As the first available register is at offset 0x8 and configures the pad
MX25_PAD_A10 the right id for this pin is 2. All other pins are off by
one, too.
This patch drops the definition MX25_PAD_RESERVE1 (together with its
only use) and decrements all following values by 1.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

This moves all the Freescale-related drivers (i.MX and MXS) to
its own subdirectory to clear the view.
