drm: Lower priority of "EDID checksum is invalid" message

The priority goes from "error" to "debug".

Connectors are polled every 10 seconds. Reading EDID is part of this
polling. However, when an invalid EDID is returned, this error message
is logged. When using Newcons for instance, having a kernel message
every 10 seconds is getting annoying.

Now that it's a debug message, it'll be logged only if hw.dri.debug is
enabled. This fix console spamming for some users.

To avoid having to explicitly test COMPILER_TYPE for setting
clang-specific or gcc-specific flags, introduce the following new
variables for use in Makefiles:

CFLAGS.clang
CFLAGS.gcc
CXXFLAGS.clang
CXXFLAGS.gcc

In bsd.sys.mk, these get appended to the regular CFLAGS or CXXFLAGS for
the right compiler.
