soc/x86: Clean up EHL kconfigs Cleanup along the same lines as the last change to APL/up_squared. Make sure all hardware configuration is at the board level where it belongs and not in the soc, don't play games with defaulting timer drivers. Unify the configuration where possible and make it clearer which setting goes with which driver. Signed-off-by: Andy Ross <andrew.j.ross@intel.com>

boards: x86: ehl_crb: Add board variant for Slim Bootloader When using Slim Bootloader the UART configuration isn't quite the same as with the UEFI BIOS. In particular, UART2 is hidden in PCIe and is instead accessible using a fixed MMIO address. Interrupts are also not supported for this UART currently. The simplest way to create builds against this special BIOS/bootloader setup seems to be to create a new board variant/definition which lets us provide a custom device tree overlay as well a dedicated Kconfig default configuration.
