[PATCH 2/3] mips:powertv: Make kernel command line size configurable (resend)

[David VomLehn <dvomlehn@cisco.com>]

Most platforms can get by perfectly well with the default command line size,
but some platforms need more. This patch allows the command line size to
be configured for those platforms that need it. The default remains 256
characters.
