Subject: [PATCH] mfd: vexpress-sysreg: initialize "site" variable

"site" variable should be initialized with 0 so that
when "site" property doesn't exist in DTB it can be handled correctly.

"0" value means board site number is motherboard (see
Documentation/devicetree/bindings/arm/vexpress.txt for details).
