mobicore: initial import of kernel driver

MobiCore kernel driver is an interface to the mobicore TEE
This version uses under_score coding style only.

MobiCore is an operating system being shipped with TZBSP
on msm chipsets. MobiCore consists of several components in
the secure world(TrustZone) and non-secure world(linux
kernel, Android user space). The MobiCore driver
communicates with the MobiCore kernel that exists in
TrustZone.

mobicore: Create branch that uses interrupt 280

MobiCore TZ to HLOS interrupt is assigned a unique SPI.
Currently it shares the SPI with EBI_ERP and moving
forward this interrupt has to be not shared in order
to allow the enablement of EBI_ERP feature..
