There is a GPIO driver for use with arty so enable the GPIO feature in
the board yaml to get some testing of it.

At this time there's no clear need to support anything other than the
A35T variant, but to simplify future extension show where the
partition size came from and document the corresponding parameter for
the A100T variant.

Add missing default for enabling CONFIG_SPI if CONFIG_FLASH is
enabled. This is needed for CONFIG_SPI_NOR.

The ARM Cortex-M1/M3 DesignStart FPGA reference designs support booting
from an off-board, memory-mapped QSPI NOR flash device. The V2C DAPlink
shield from ARM Ltd. provides support for this feature.
If the board/shield is not configured for booting from the QSPI NOR
device, that same device is available as a regular QSPI NOR flash
device.
The presense of a shield configured for QSPI NOR flash boot is indicated
through an IRQ line used as a level-detect, non-interrupt signal.
Introduce a board specific devicetree binding for the DAPLink QSPI MUX
and provide a board specific API accessing it. Automatically set the
QSPI MUX to to provide regular QSPI NOR flash access if the board/shield
is not configured for memory-mapped QSPI NOR flash boot.

The ARM Cortex-M1/M3 DesignStart FPGA reference designs both use IRQ 7
(the last IRQ line) as a level-detect non-interrupt signal to determine
whether the V2C-DAPLINK shield is installed. Thus IRQ 7 cannot be used
as a regular IRQ line.
