This switch family can have up to 8 ports {0..7}. However, INDIRECT_ACCESS_ADDRESS_PHYNUM_MASK was using 2 bits instead of 3, dropping the most significant bit during indirect register reads and writes. Reading or writing ports 4, 5, 6, and 7 registers was actually manipulating, respectively, ports 0, 1, 2, and 3 registers.
rtl8365mb_phy_{read,write} will now returns -EINVAL if phy is greater than 7.
