serial: allow 8250 to be used on sparc
This requires three changes:
1) Remove !SPARC restriction in Kconfig.
2) Move Sparc specific serial drivers before 8250, so that serial
console devices don't change names on us, even if 8250 finds
devices.
3) Since the Sparc specific serial drivers try to use the
same major/minor device namespace as 8250, some coordination
is necessary. Use the sunserial_*() layer routines to allocate
minor number space within TTY_MAJOR when CONFIG_SPARC.
This has no effect on other platforms.
Thanks to Josip Rodin for bringing up this issue and testing
plus debugging various revisions of this patch.
