kernel: broadcom-wl: multiple fix to make the package compilable again
Add multiple patch to make the package compilable again.
Aside from some fixup of obvius wrong code, some real fix were needed.
This fix any compilation warning found on compiling the package on
bcm47xx. (omitted since they are too much)
The real problem of this package was the missing MODULE_LICENSE now
mandatory even without WERROR. Set to Proprietary.
And the big blocker is that Broadcom provided an object file targetting
an old kernel version.
The module on modprobe try to find the symbol printk but printk was
dropped and replaced to _printk.
To handle this change we use objcopy tool to rename the symbol to the
new name permitting a correct modprobe and creation of .ko
