Subject: [PATCH 5.10 047/125] firmware: arm_scmi: Add SMCCC discovery dependency in Kconfig

From: Etienne Carriere <etienne.carriere@...aro.org>

[ Upstream commit c05b07963e965ae34e75ee8c33af1095350cd87e ]

ARM_SCMI_PROTOCOL depends on either MAILBOX or HAVE_ARM_SMCCC_DISCOVERY,
not MAILBOX alone. Fix the depedency in Kconfig file and driver to
reflect the same.
