PATCH 1/1 Bluetooth: btbcm: Use strreplace() in btbcm_get_board_name()

The original code works but it's a bit iffy. The end of loop test should be something like "board_type[i] != '\0'" but instead it is is "i < board_type[i]". Fortunately, those two tests are equivalent so long as the "board_type" is not an empty string.

It's much simpler to just call strreplace() instead.

I think I just copied this code from the BRCM wifi driver for the combo chip, did you patch that too?

Uh, I did but it got lost (my fault). I will resend that. Thanks!
