mb/google/poppy/variants/rammus: revise rammus settings

The changes include:
1. Move the build board directory from poppy to rammus.
2. Add audio, gpio, memory and device tree configuration base on the proto
board schematics.
3. IccMax is set to 28A because of the AML requirement, the AcLoadline and
DcLoadline need to be fine tuned later.
4. The usb2_ports' parameter need to be fine tuned later. Currently,
for the ports located on the mainboard, set it to USB2_PORT_SHORT.
For the others on the daughterboard, set it to USB2_PORT_LONG.

BUG=b:111579386
BRANCH=Master
TEST=Build pass.
