staging: sb105x: clean up interface type test
IIR_RS232 is zero so "if (IIR_RS232 == (b_ret & IIR_RS232))" is always
true so RS232 was always chosen by default. The test should be
"if (0 == (b_ret & 0x30)) { ". The other tests should also be in that
format.
This does change how the code works... If 0x30 is set then it now
defaults to RS232 instead of RS485.
