The `msm-fb-refresher` updates the screen for msm based devices. It is
not needed for all devices, so we had some extra code in the initramfs,
that would only add it when the `deviceinfo_msm_refresher` variable was
set. However, we are able now to add files to initramfs hooks, so this
hack can be removed and simplify everything.
Changes:
* Remove `deviceinfo_msm_refresher` from all deviceinfos
* Add sanity check for it
* Move all `deviceinfo` sanity checks to an extra function
* `postmarketos-mkinitfs`: remove code for msm refresher
* `msm-fb-refresher`: add initramfs hook
* device-*: add postmarketos-base to depends
* aportgen: add postmarketos-base to depends
* Add test case
* postmarketos-base: Don't depend on devicepkg
* msm-fb-refresher: Enable service in post-install
* Rename deviceinfo variable flash_methods to flash_method
* Update pmb.config.deviceinfo_attributes / add sanity check
* Add test case that parses all deviceinfo files
@drebrez deserves much credit for this one for all the testing,
bisecting and for fixing everything. Thank you very much!

* devices which need a custom weston.ini ship it with a install_if
subpackage, so it only gets installed when weston is installed. This
sounds complicated, but is actually pretty clean in the APKBUILD.
* postmarketos-ui-weston: has a weston.ini.default, which enables
xwayland and uses fbdev as backend (because that's what most
devices use!). It defaults to the weston.ini.default if there is no
weston.ini (as installed by the device package).
* changed spaces to tabs for consistency, general minor refactoring of
device-APKBUILDs
