Kai Song 27f2e5b914 mfd: altera-sysmgr: Fix a mistake caused by resource_size conversion ...

[ Upstream commit fae2570d62 ]

The resource_size defines that:
	res->end - res->start + 1;
The origin original code is:
	sysmgr_config.max_register = res->end - res->start - 3;

So, the correct fix is that:
	sysmgr_config.max_register = resource_size(res) - 4;
