Aleksandr Mishin 5a8f4be9b4 remoteproc: imx_rproc: Skip over memory region when node value is NULL
[ Upstream commit 2fa26ca8b786888673689ccc9da6094150939982 ]

In imx_rproc_addr_init() "nph = of_count_phandle_with_args()" just counts
number of phandles. But phandles may be empty. So of_parse_phandle() in
the parsing loop (0 < a < nph) may return NULL which is later dereferenced.
Adjust this issue by adding NULL-return check.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
