qed: Add '_GTT' suffix to the IRO RAM macros

GTT (Global translation table) is a fast-access window in the BAR into
the register space, which only maps certain register addresses.
This change helps enforce that only those addresses which are indeed
mapped by the GTT are being accessed through it.

Adding the '_GTT' suffix to the IRO FW memory (“RAM”) macros that
access GTT-able region in FW memories (“RAM”) and use GTT macros
to access RAM BAR from drivers.

qed: Remove e4_ and _e4 from FW HSI

The existing qed/qede/qedr/qedi/qedf code uses chip-specific naming in

The new FW version introduced a generic naming convention in HSI
in-which the same code will be used across different versions
for simpler maintainability. It also eases in providing support for
new features.

With this patch every "_e4" or "e4_" prefix or suffix is not needed
anymore and it will be removed.

Management is a firmware responsible for link configuration and

Running FW (or fastpath FW) is an embedded microprogram implementing
all the packet processing, offloads, etc. This FW is being loaded
on each start by the driver from FW binary blob.

net: qed: fix buffer overflow on ethtool -d

When generating debug dump, driver firstly collects all data in binary
form, and then performs per-feature formatting to human-readable if it
is supported.

For ethtool -d, this is roughly incorrect for two reasons. First of all,
drivers should always provide only original raw dumps to Ethtool without
any changes.
The second, and more critical, is that Ethtool's output buffer size is
strictly determined by ethtool_ops::get_regs_len(), and all data *must*
fit in it. The current version of driver always returns the size of raw
data, but the size of the formatted buffer exceeds it in most cases.
This leads to out-of-bound writes and memory corruption.

Address both issues by adding an option to return original, non-formatted
debug data, and using it for Ethtool case.

v2:
- Expand commit message to make it more clear;
- No functional changes.
