wil6210: support boot loader struct v0 & v1

Browse Source 
There are 2 versions of boot loader struct: v0 and v1.
In the v1, boot loader build version added; as well as
RF status.

Support both versions.

Boot loader structure v1 has RF status; ignore RF error if firmware
not going to be loaded; driver can still be used to interact with the HW
