firewire: core: provide isoc header buffer size outside card driver
For single-channel isochronous contexts, the header storage size is
hard-coded to PAGE_SIZE. which is inconvenient for protocol
implementations requiring more space.
This commit refactors the code to obtain the header storage size outside
the 1394 OHCI driver.
