bnxt_en: Fix bnxt_refclk_read()
The upper 32-bit PHC register is not latched when reading the lower
32-bit PHC register. Current code leaves a small window where we may
not read correct higher order bits if the lower order bits are just about
to wrap around.
This patch fixes this by reading higher order bits twice and makes
sure that final value is correctly paired with its lower 32 bits.
Fixes: 30e96f487f64 ("bnxt_en: Do not read the PTP PHC during chip reset")
