serial: Make full device search optional
Commit 608b0c4ad4e5ec0c ("serial: Use next serial device if probing fails")
added code to search for more serial devices if the default one was not
probed correctly.
Unfortunately, that breaks omap3_evm. So while investigating why that is
the case, let's disable the full search for everyone but bcm283x where it
is needed.
