x86: qemu: fix ACPI Kconfig options

CONFIG_GENENRATE_ACPI_TABLE controls the generation of ACPI table which
uses U-Boot's built-in methods and CONFIG_QEMU_ACPI_TABLE controls whether
to load ACPI table from QEMU's fw_cfg interface.

But with commit "697ec431469ce0a4c2fc2c02d8685d907491af84 x86: qemu: Drop
our own ACPI implementation", there is only one way to support ACPI table
for QEMU targets which is the fw_cfg interface. Having two Kconfig options
for this purpose is not necessary any more, so this patch consolidates
the two.

          The Advanced Configuration and Power Interface (ACPI) specification
          provides an open standard for device configuration and management
