net: lan743x: Modify the EEPROM and OTP size for PCI1xxxx devices

[ Upstream commit 3b9935586a9b54d2da27901b830d3cf46ad66a1e ]

Maximum OTP and EEPROM size for hearthstone PCI1xxxx devices are 8 Kb
and 64 Kb respectively. Adjust max size definitions and return correct
EEPROM length based on device. Also prevent out-of-bound read/write.
