feat(intel): add support for F2S and S2F bridge SMC with mask to enable, disable and reset bridge
This adds F2S and S2F bridge enable, disable and reset
sequence to enable, disable and reset properly the bridges
in SMC call or during reset.
The reset is also maskable as the SMC from uboot can
pass in the bridge mask when requesting for bridge
enable or disable.
