media: ddbridge: fixup checkpatch-strict issues
Fixes several alignment, braces, space-before-cast, camelcase et al issues reported by checkpatch --strict, plus a few more checkpatch didn't report. Three checks are left after this though: - one CamelCase in ddbridge-core, related to defines/vars/enums referenced from the stv090x demod driver - one macro argument reuse in ddbridge-core aswell - one unbalanced braces around else in ddbridge-main, which is due to #ifdefs related to CONFIG_PCI_MSI, which preferrably should be kept as-is for readability.
