Commit 6559a7e8 ("cxgb4: Cleanup macros so they follow the same
style and look consistent") introduced a regression where reading MC1
memory in adapters where MC0 isn't present or MC0 size is not equal to MC1
size caused the adapter to crash due to incorrect computation of memoffset.
Fix is to read the size of MC0 instead of MC1 for offset calculation

Add new Common Code routines to retrieve Firmware Device Log
parameters from PCIE_FW_PF[7]. The firmware initializes its Device Log very
early on and stores the parameters for its location/size in that register.
Using the parameters from the register allows us to access the Firmware
Device Log even when the firmware crashes very early on or we're not
attached to the firmware

When doing reads and writes to adapter memory via the PCI-E Memory Window
interface, data gets swizzled on 4-byte boundaries on Big-Endian systems
because we need to account for the register read/write interface which
incorporates a swizzle onto the Little-Endian PCI-E Bus.

Various patches have ended up changing the style of the symbolic macros/register
defines to different style.

As a result, the current kernel.org files are a mix of different macro styles.
Since this macro/register defines is used by different drivers a
few patch series have ended up adding duplicate macro/register define entries
with different styles. This makes these register define/macro files a complete
mess and we want to make them clean and consistent. This patch cleans up a part
