The driver for the Freescale P3060 QDS got added by commit 96cc017c5b
("[...] Add support for P3060QDS board"). Its Kconfig entry selects
MPC8xxx_GPIO. But at the time that driver got added MPC8xxx_GPIO was
already renamed to GPIO_MPC8XXX, by commit c68308dd50 ("gpio: move
mpc8xxx/512x gpio driver to drivers/gpio").
So make this driver select GPIO_MPC8XXX.

Fixes the PS3 bootup hang introduced in 3.0-rc1 by:
commit 317f394160
sched: Move the second half of ttwu() to the remote cpu
Move the PS3's LV1 EOI call lv1_end_of_interrupt_ext() from ps3_chip_eoi()
to ps3_get_irq() for IPI messages.
If lv1_send_event_locally() is called between a previous call to
lv1_send_event_locally() and the coresponding call to
lv1_end_of_interrupt_ext() the second event will not be delivered to the
target cpu.
The PS3's SMP IPIs are implemented using lv1_send_event_locally(), so if two
IPI messages of the same type are sent to the same target in a relatively
short period of time the second IPI event can become lost when
lv1_end_of_interrupt_ext() is called from ps3_chip_eoi().

Normally logical and hard cpu ID are the same, however in same cases like
on the P3060 they may differ. Where the logical is 0..5, the hard id
goes 0,1,4..7. This can causes issues for places we utilize PIR to index
into array like in debug exception handlers for finding the exception
stack.

Standarize and document the FPGA nodes used on Freescale QorIQ reference
boards. There are different kinds of FPGAs used on the boards, but
only two are currently standard: "pixis", "ngpixis", and "qixis". Although
there are minor differences among the boards that have one kind of FPGA, most
of the functionality is the same, so it makes sense to create common
compatibility strings.
We also need to update the P1022DS platform file, because the compatible
string for its PIXIS node has changed. This means that older kernels are
not compatible with newer device trees. This is not a real problem, however,
since that particular function doesn't work anyway. When the DIU is active,
the PIXIS is in "indirect mode", and so cannot be accessed as a memory-mapped
device.
