arch/x86/acpigen: wrap _PLD in a package
The ACPI spec has an asl example for _PLD in the form:
Name (_PLD, Package (0x01) { ToPLD (PLD_Revision = 0x2) })
When I ported this to acpigen and diffed the results I noticed that
the binary blob was no longer provided within a package. The ACPI
spec (section 6.1.8 in version 6.2) defines _PLD as "a variable-length
Package containing a list of Buffers". This commit changes
acpigen_write_pld to use a package (the one existing caller I found
isn't wrapping the result in a package so it doesn't look like
it was intended for the callers of acpigen_write_pld to be responsible
for using a package.
BUG=none
BRANCH=none
TEST=Verified that after this change a package is use and the result
of acpigen matches what was used in the original asl.
