Merge https://gitlab.denx.de/u-boot/custodians/u-boot-x86

- New timer API to allow delays with a 32-bit microsecond timer
- Add dynamic ACPI structs (DSDT/SSDT) generations to the DM core
- x86: Enable ACPI table generation by default
- x86: Enable the copy framebuffer on Coral
- x86: A few fixes to FSP2 with ApolloLake
- x86: Drop setup_pcat_compatibility()
- x86: Primary-to-Sideband Bus minor fixes
