Subject: [PATCH V3 2/4] remoteproc: imx_rproc: enlarge IMX7D_RPROC_MEM_MAX

From: Peng Fan <peng.fan@....com>

8 is not enough when we need more, such as resource table for remote cores
that booted before Linux Kernel, so enlarge IMX7D_RPROC_MEM_MAX to 32.
And also rename it to IMX_RPROC_MEM_MAX which make more sense.
