device-samsung-expressatt: Switch to generic pmOS kernels

devices.config being dropped from linux-next partially broke expressatt
as the mainline kernels do not enable peripherals that are needed
by expressatt. Let's instead add it to kconfig-generic.toml and use
postmarketOS's generic kernels instead of Alpine's.
