bnxt_en: Fix ethtool -d byte order for 32-bit values

Browse source

[ Upstream commit 02e8be5a03 ]

For version 1 register dump that includes the PCIe stats, the existing
code incorrectly assumes that all PCIe stats are 64-bit values.  Fix it
by using an array containing the starting and ending index of the 32-bit
values.  The loop in bnxt_get_regs() will use the array to do proper
endian swap for the 32-bit values.
