octeontx2-af: Fix SDP MAC link credits configuration
Current driver allows only packet size < 512B as SDP_LINK_CREDIT
register is set to default value.
This patch fixes this issue by configure the register with
maximum HW supported value to allow packet size > 512B.
Fixes: 2f7f33a09516 ("octeontx2-pf: Add representors for sdp MAC")
