Limit the size of SRAM available for the rest of kernel via genalloc API's to

Certainly not, if the can controller need the SRAM, they have to
allocate it properly.
I'm not sure that bosh mcan driver can be used with dynamic allocation
of SRAM. Is it what you're thinking about?
In the meantime, I'm taking the CAN patches of this series as they match
what we currently do for other users of mcan driver on other SoCs.
