[ Upstream commit 263ade7166a2e589c5b605272690c155c0637dcb ]
EIC controller have unfixed numbers of banks on different Spreadtrum SoCs, and each bank has its own base address, the loop of getting there base address in driver should break if the resource gotten via platform_get_resource() is NULL already. The later ones would be all NULL even if the loop continues.
