INGPADBOUNDARY_MASK is already shifted. No need to shift it again. On reloading
a driver it was resulting in a bad SGE FL MTU sizes [1536, 9088] error. This
only causes an issue on systems that have L1 cache size of 32B, 128B, 512B,
2048B or 4096B.

This patch adds a new common code routine to upgrade an adapter's
firmware.  This routine handles all of the complexities of working with the
the existing adapter firmware in order to quiesce the adapter and uP, etc.
For an automatic upgrade it will send a HELLO command to check if cxgb4
want/can upgrade firmware, i.e. if cxgb4 is MASTER and has newer firmware
that it wants to load and call the new common code routine t4_fw_upgrade.
Note that it should not issue a RESET command after a successful firmware
upgrade.

Starting with T4 firmware version 1.3.11.0 the firmware now supports device
configuration via a Firmware Configuration File. The Firmware Configuration
File was primarily developed in order to centralize all of the configuration,
resource allocation, etc. for Unified Wire operation where multiple
Physical / Virtual Function Drivers would be using a T4 adapter simultaneously.

The Firmware Configuration file can live in three locations as shown below
in order of precedence.
1) User defined configuration file: /lib/firmware/cxgb4/t4-config.txt
2) Factory Default configuration file written to FLASH within
   the manufacturing process.
3) Hardwired driver configuration.

This patch implements two new functions t4_mem_win_read and t4_memory_read.
These new functions can be used to read memory via the PCIE memory window.
Please note, for proper execution of these functions PCIE_MEM_ACCESS_BASE_WIN
registers must be setup correctly like how setup_memwin in the cxgb4 driver
does it.

Add platform-specific callback functions for interrupts.  This is
needed to do a single read-clear of the CAUSE register and then call
out to platform specific functions for DB threshold interrupts and DB
drop interrupts.

Add t4_mem_win_read_len() - mem-window reads for arbitrary lengths.
This is used to read the CIDX/PIDX values from EC contexts during DB
drop recovery.

Add t4_fwaddrspace_write() - sends addrspace write cmds to the fw.
