[MTD] physmap: make physmap compat explicit
The current method for always showing physmap compat address, size, and width is a bit confusing. If length is set to 0, then the address and width are still shown but silently unused. The physmap code itself already has logic which sets compat based on length, so just pull that out and into the Kconfig to make everything clear.
