machines: replace Intel-SCH config-aggregator kernel patches with direct configs

bhouse-nexthop · bhouse-nexthop · commit 84e24aa14bbc · 2026-07-13T20:38:38.000Z
Nine x86 platforms (the Dell C2xxx/S-series family + agema_ag7648c) each
carried a kernel patch whose sole purpose was to add a platform Kconfig
symbol that select()ed a fixed set of standard Intel SoC options
(I2C_ISCH, I2C_ISMT, GPIO_SCH, MFD_CORE, LPC_SCH) with no driver code.
Replace each with those CONFIG_* set directly in the machine kernel
config and drop the patch.

The aggregator was each platform's only kernel patch, so with it gone they
carry no version-bound kernel code: drop their LINUX_VERSION pins too and
let them ride the default kernel (6.18 LTS, which builds under GCC 14).
The five options were verified to survive `make olddefconfig` against the
6.18 base config.
