The blamed commit introduced the following smatch warning in the
function lan9662_otp_wait_flag_clear:
drivers/nvmem/lan9662-otpc.c:43 lan9662_otp_wait_flag_clear() warn: signedness bug returning '(-110)'
Fix this by changing the return type of the function
lan9662_otp_wait_flag_clear() to be int instead of bool.

nvmem: lan9662-otp: Fix compatible string2022-11-10T17:45:01ZHoratiu Vulturhoratiu.vultur@microchip.com2022-09-28T19:51:12Zurn:sha1:1aeb122d214b92474c86fde00a03d6e2d69381b5
The device tree bindings for lan9662-otp expects the compatible string
to be one of following compatible strings:
microchip,lan9662-otpc
microchip,lan9668-otpc
The problem is that the lan9662-otp driver contains the
microchip,lan9662-otp compatible string instead of
microchip,lan9662-otpc.
Fix this by updating the compatible string in the driver.

Add support for OTP controller available on LAN9662. The OTPC controls
the access to a non-volatile memory. The size of the memory is 8KB.
The OTPC can access the memory based on an offset.
Implement both the read and the write functionality.
