drivers/net: update format specifier on lan9250 driver

[fdcavalcanti]

Summary

Fix print statement for uint8 and uint16 types.
Required due to efforts on fixing #15755 .

I had recently sent a PR on this same driver but missed a couple of lines.

Error example:

In file included from net/lan9250.c:34:
net/lan9250.c: In function 'lan9250_wait_ready':
net/lan9250.c:620:12: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'uint32_t' {aka 'long unsigned int'} [-Wformat=]

Impact

• Impact on user: NO.
• Impact on build: This will throw erros when fixing [BUG] arch/xtensa: wrong definition for _int32_t and _uint32_t #15755. It can be merged now since it won't affect current builds.
• Impact on hardware: NO.
• Impact on documentation: NO.
• Impact on security: NO.
• Impact on compatibility: NO.

Testing

This test simply builds the binary and checks for compilation errors.
Unfortunately I don't have this device to test (requires external LAN9250). If someone has, please speak up!

Building

• ./tools/configure.sh esp32s3-devkit:eth_lan9250
• make

Results

No build errors.

Can we go forward with this?

Unfortunately, we need to wait until more people vote, I wish more people were actually interested in becoming reviewers. By the way, are you interested in becoming a reviewer?

Thanks @fdcavalcanti :-)

• The uint16_t address should use 0x%04"PRIx16 as 8-bit data is represented by two ascii hex while 16-bit by four ascii hex right?
• If we use 0x%02"PRIx8 for uint16_t type then half of the data is cut.
• Personally I prefer PRIX16 in order to get upper case ascii hex but the code uses already lowercase so its okay to leave its lowercase :-P

Well, most of us are volunteers working in a so called free moments so its not always possible to respond rapidly as we would wish, help is needed.. for instance its 0308AM Friday/Saturday night here and I just did my first Saturday coffee "today" :D :D

Sorry about the delay. Carnival week here in Brazil :)
Sure, I would like to help on reviews @acassis.

CI failed, seems random, restarted. lets wait for the all tests to complete before merge :-)

Allright CI passed :-)
