[PATCH 4.19 027/639] ARM: qcom_defconfig: Enable MAILBOX

[Greg Kroah-Hartman]

From: Frank Rowand <frank.rowand@xxxxxxxx>

[ Upstream commit 54c2678cd198f61555796bbda5e1727e6e1858f1 ]

Problem:
ab460a2e72da ("rpmsg: qcom_smd: Access APCS through mailbox framework"
added a "depends on MAILBOX") to RPMSG_QCOM_SMD, thus RPMSG_QCOM_SMD
becomes unset since MAILBOX was not enabled in qcom_defconfig and is
not otherwise selected for the dragonboard.  When the resulting
kernel is booted the mmc device which contains the root file system
is not available.

Fix:
add CONFIG_MAILBOX to qcom_defconfig

Fixes: ab460a2e72da ("rpmsg: qcom_smd: Access APCS through mailbox framework"
added a "depends on MAILBOX")
