[meta-intel] [PATCH 1/2] intel-corei7-64: add machine configurations specific to leafhill bsp

[Rebecca Chang Swee Fun]

We would like to enable new BSP for Intel Atom E3900 SoC based platforms.
This will help us to consolidate BSP into intel-common and we can use
KERNEL_FEATURES to select target BSP to compile.

Leaf Hill uses different serial console port setup. Hence this
mechanism are in place to enable new bsp with existing machine
configurations file.

Leaf Hill BSP also required additional kernel stack protector
settings to compile kernel with security defense enabled.
