google-walleye: Fix early framebuffer
It looks like *not* having `quiet` in the kernel cmdline somehow makes
the early init of the framebuffer fail.
I don't know the exact difference, but lowering loglevel rather than
using quiet doesn't work here.
In addition, this changes
"raid=noautodetect"
"androidboot.fastboot=1"
"buildvariant=eng"
+
+ # Using `quiet` fixes early framebuffer init, for stage-1
+ "quiet"
];
generate_bootimg = "true";
