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: Use enum as per FW 8.59.1.0 in qed_iro_hsi.h

qed_iro_hsi.h contains HSI changes related to storm memories access.
Existing code is based on hard-coded index.
Use enum as defined for FW HSI 8.59.1.0, instead of hard-coded index.

This patch also removes unnecessary header file inclusion.

qed: Split huge qed_hsi.h header file

The qed_hsi.h is a huge header file containing HSI (Hardware Software
Interface) definitions of storm memory access, debug related, general
and management firmware specific. In order to have a better
code-organization HSI definition, this patch split the code across
multiple files, i.e.
- storm memory access HSI : qed_iro_hsi.h
- debug related HSI : qed_dbg_hsi.h
- Management firmware HSI : qed_mfg_hsi.h
- General HSI : qed_hsi.h

In addition, this patch also fixes existing checkpatch warnings and
few important checks.
