[PATCH] Compilation fix for ES7000 when no ACPI is specified in config (i386)

ES7000 platform code clean up for compilation errors and a warning.
Ifdef'd the ACPI related parts in the ES7000 platform code.  They were
causing compile errors in certain configuration (without ACPI defined).  I
think this approach would be best (as opposed to Kconfig changes) since it
only touches the subarch...
