Subject: [PATCH -next] ACPI: SBS: remove unused variable 'SMBUS_PEC'

drivers/acpi/sbshc.h:18:17: warning:
 SMBUS_PEC defined but not used [-Wunused-const-variable=]

SMBUS_PEC is never used since introduction in
commit 91087dfa51a2 ("ACPI: SBS: Split host
controller (ACPI0001) from SBS driver (ACPI0002)"),
so just remove it.
