[PATCH 1/2] arm: socfpga: agilex5: select GPIOLIB

[Michael Tretter]

GPIOLIB is disabled on the Agilex 5 Board, because it adds about 1k to
the piggy data for barebox proper. During experiments, this added about
1k to the FSBL image, which pushed the size over some undocumented limit
that prevented the board from booting.

Since there is no actual size check for the barebox image, there is no
guarantee that the socfpga-agilex5_defconfig will result in an image
that meets the size restriction. Therefore, some tuning of the config
and disabling of various driver is required for some specific board,
anyway.

Enabling the GPIOLIB for one board will also enable it for all other
boards, unless there is a dependency that GPIOLIB is disabled and makes
board mutually exclusive.

If the piggy data is removed from the FSBL and loaded as SSBL, the size
of the piggy data is not restricted anymore, and the option has not
drawback anymore.

Therefore, select and enable GPIOLIB because its features are very
useful, and not having it causes more trouble for questionable gain.
