Subject: [PATCH] brcmfmac: enlarge buffer size of caps to 512 bytes
The buffer size of return of cap iovar is greater than 256 bytes in some
firmwares. For instance, the return size of cap iovar is 271 bytes in 4373
13.10.246.79 firmare. It makes feature capability parsing failed because
caps buffer is default value.
So we enlarge caps buffer size to 512 bytes and add the error print for
cap iovar error.

Subject: [PATCH] brcmfmac: Fix check for ISO3166 code
The commit "regulatory: add NUL to request alpha2" increases the length of
alpha2 to 3. This causes a regression on brcmfmac, because
brcmf_cfg80211_reg_notifier() expect valid ISO3166 codes in the complete
array. So fix this accordingly.
