[PATCH] ACPI / property: Export a couple of symbols.

[David Daney <ddaney.cavm@gmail.com>]

From: David Daney <david.daney@cavium.com>

The acpi_dev_prop_read() and acpi_dev_prop_read_single() can be called
by drivers.  Add EXPORT_SYMBOL_GPL to them to allow use by modular
drivers.  This makes them consistent with acpi_dev_get_property() and
acpi_node_get_property_reference() which are already exported.

Signed-off-by: David Daney <david.daney@cavium.com>

FWIW: We hope to submit soon Cavium Thunder networking patches that
fail under modular builds without these exports.
