tty: mips_ejtag_fdc: fix one more u8 warning

Browse Source 
[ Upstream commit 6dd1de91e7 ]

The LKP robot complains about:
   drivers/tty/mips_ejtag_fdc.c:1224:31: error: incompatible pointer types passing 'const char *[1]' to parameter of type 'const u8 **' (aka 'const unsigned char **')

Fix this by turning the missing pieces (fetch from kgdbfdc_wbuf) to u8
too. Note the filling part (kgdbfdc_write_char()) already receives and
stores u8 to kgdbfdc_wbuf.

Fixes: ce7cbd9a6c ("tty: mips_ejtag_fdc: use u8 for character pointers")
