[ptxdist] [PATCH] optee-client: add config option for RPMB emulation

["Sven Püschel" <s.pueschel@pengutronix.de>]

From: Michael Tretter <m.tretter@pengutronix.de>

RPMB emulation is enabled by default in the tee-supplicant. In a
production system, the RPMB shall be backed by the eMMC.

Add an option to disable RPMB emulation.
