brcmfmac has been broken on my cubietruck with a BCM43362:

brcmfmac: brcmf_chip_recognition: found AXI chip: BCM43362, rev=1
brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0:
        Apr 22 2013 14:50:00 version 5.90.195.89.6 FWID 01-b30a427d

since commit 53036261: "brcmfmac: update core reset and disable routines".

The problem is that since this commit brcmf_chip_ai_resetcore no longer sets
BCMA_IOCTL itself before bringing the core out of reset, instead relying on
brcmf_chip_ai_coredisable to do so. But brcmf_chip_ai_coredisable is a nop
of the chip is already in reset. This patch modifies brcmf_chip_ai_coredisable
to always set BCMA_IOCTL even if the core is already in reset.

This fixes brcmfmac hanging in firmware loading on my board.

In the enter and exit download sequence the chip core info was checked
for presence of CM3 ARM core. If found it would enter download state for
the CM3. However, on devices that have a CM3 and CR4 this is not correct
and the CR4 should be used to enter download state. This patch changes
the ARM core lookup giving CR4 precedence.
