x86: acpi: Add DMA descriptors for I2C1 on Intel Tangier
Intel Tangier SoC has a general purpose DMA which can serve to speed up
communications on SPI and I2C serial buses.
Provide DMA descriptors to utilize this capability in the future.
Note, I2C6, which is available to user, has no DMA request lines connected.

x86: zimage: Remove acpi_rsdp_addr propagation to kernel boot parameters
As of today, the proposal of adding "acpi_rsdp_addr" to the kernel
boot protocol does not make its way to the kernel mainline. This
creates some confusion if we leave it in the U-Boot code base.
Remove it for now until we have a clear picture with kernel upstream.
Note this eventually does a partial revert to commit 3469bf427454
("x86: zImage: Propagate acpi_rsdp_addr to kernel via boot parameters")
