Subject: [PATCH] drivers: firmware: psci: avoid BIT() macro usage in
 PSCI_1_0_OS_INITIATED

The BIT() macro is not available in UAPI headers, so let's replace
it with similarly defined _BITUL() macro provided by <linux/const.h>.

Fixes: 60dd1ead65e8 ("drivers: firmware: psci: Announce support for OS initiated suspend mode")
Signed-off-by: Eugene Syromiatnikov <esyr@...hat.com>
