Set the RDC permission for this peripheral: the RDC controls which
processor can access to this peripheral. User can select to assign this
peripheral to the M4 processor, A9 processor or both with R/W or RW
permissions. To set wanted permission a user should use the helper
macro RDC_DOMAIN_PERM(domain,permission) where domain must be one of
M4_DOMAIN_ID or A9_DOMAIN_ID and permission one among
RDC_DOMAIN_PERM_NONE, RDC_DOMAIN_PERM_W, RDC_DOMAIN_PERM_R,
RDC_DOMAIN_PERM_RW. Example to allow both processor to read/write to
this peripheral a user should put:
rdc = <(RDC_DOMAIN_PERM(A9_DOMAIN_ID, RDC_DOMAIN_PERM_RW) |
RDC_DOMAIN_PERM(M4_DOMAIN_ID, RDC_DOMAIN_PERM_RW))>;

Set the RDC permission for specified peripheral: Resource Domain Controller (RDC)
supports flexible configuration on IP’s access permission, each individual IP can,
for example, be configured as A-core only or M-core only. This property uses some
macros defined in 'include/zephyr/dt-bindings/rdc/imx_rdc.h' to configure current
peripheral's access permission.
For example to allow both A53 and M7 Core to have read/write permission to current
peripheral:
rdc = <(RDC_DOMAIN_PERM(A53_DOMAIN_ID, RDC_DOMAIN_PERM_RW)|\
RDC_DOMAIN_PERM(M7_DOMAIN_ID, RDC_DOMAIN_PERM_RW))>;
