[PATCH v1 4/6] x86/boot: Allow longer parameter list for earlyprintk

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

Allow longer parameter list, up to 64 characters, for earlyprintk
to support new coming parameters.

If the parsed string is longer than this buffer it will be cut up by
the buffer size.

No functional change intended.

Note, that 'console' case is already covered.
