Subject: [PATCH 01/15] fpga: dfl-fme-mgr: fix FME_PR_INTFC_ID register address.

From: Wu Hao <hao.wu@...el.com>

FME_PR_INTFC_ID is used as compat_id for fpga manager and region,
but high 64 bits and low 64 bits of the compat_id are swapped by
mistake. This patch fixes this problem by fixing register address.
