Commit Message

Separate out the declaration of usb related function into another
if/else condition in btmtk.h, avoiding function-declaration issue
happened when CONFIG_BT_HCIBTUSB was defined but CONFIG_BT_HCIBTUSB_MTK
wasn't.

'btmtk_usb_subsys_reset';
ISO C99 and later do not support implicit
function declarations [-Wimplicit-function-declaration]
'alloc_mtk_intr_urb';
ISO C99 and later do not support implicit
function declarations [-Wimplicit-function-declaration]
'btmtk_usb_setup';
ISO C99 and later do not support implicit
function declarations [-Wimplicit-function-declaration]
'btmtk_usb_shutdown';ISO C99 and later do not support
implicit function declarations [-Wimplicit-function-declaration]
