BrcmPatchRAM2 fails when in Clover/kexts

[RehabMan]

I don't use it from Clover/kexts, but...

This is the situation:

• BrcmPatchRAM2 loads (along with BrcmFirmwareData) via injection at boot
• it loads firmware, all is fine... probe/exit
• because BrcmPatchRAM2 is not resident (unlike BrcmPatchRAM.kext), the kernel will eventually unload it
• now sleep happens, then wake
• firmware needs to be loaded.
• the IOKit personality is present in the io catalog, but the kext is gone from memory
• the kernel tries to load it, but guess what... it can't find it (it doesn't know to look on EFI partition!)

Result: failure of BT on wake

This results from the separation of BrcmFirmwareStore from BrcmPatchRAM2 objects. When they were one kext, BrcmFirmwareStore would keep BrcmPatchRAM2 loaded.

The fix would be to have a small object staying resident in BrcmPatchRAM2.kext (under IOResource). That way the kext will stay loaded and will be available upon wake from sleep.

Fixed.
