x86: zimage: Remove acpi_rsdp_addr propagation to kernel boot parameters

Browse Source 
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 3469bf4274
("x86: zImage: Propagate acpi_rsdp_addr to kernel via boot parameters")
