[PATCH v2 0/8] Use logging feature instead of FPGA_DEBUG

[Alexander Dahl <ada@thorsis.com>]

Hei hei,

while working on FPGA support for a new device I discovered debug
logging in some FPGA drivers is still done as in the old days.  Bring
that to what I thougt would be the currently preferred approach.

Notes: Adding those Kconfig symbols in patch 4 is just to be able to
build those two old drivers.

All drivers touched were build tested with sandbox64_defconfig and GCC8
on Debian GNU/Linux 10 (buster).

Lines with other possibly questionable output were not touched, only
what seemed to be designated debug output, and only for FPGA drivers
having that ancient FPGA_DEBUG / PRINTF macros, so there's room for
future improvements.

Changelog:

v1 -> v2:

- Rebased on master
- Added patch to introduce new FPGA uclass in front of the other patches
- Use that new uclass as log category
- Slightly reworded cover letter
