MIPS: TXx9: Make firmware parameter passing more robust
When booting Linux on a txx9 board with VxWorks boot loader, it crashes in prom_getenv(), as VxWorks doesn't pass firmware parameters in a0-a3 (in my case, the actual leftover values in these registers were 0x80002000, 0x80001fe0, 0x2000, and 0x20). Make the parsing of argc, argv, and envp a bit more robust by checking if argc is a number below CKSEG0, and argv/envp point to CKSEG0.
