Subject: be2net: add a few log messages

This patch adds the following log messages to help debugging
failure cases:
1) log FW version number: this is useful when driver initialization
fails and the FW version number cannot be queried via ethtool
2) per function resource limits for BEx chips: these values are
currently being printed only for Skyhawk and Lancer
3) PCI BAR mapping failure
4) function_mode/caps queried from FW: this helps catch any FW bugs
that could advertise wrong capabilities to the driver

Subject: be2net: shorten AMAP_GET/SET_BITS() macro calls

The AMAP_GET/SET_BITS() macro calls take structure name as a parameter
and hence are long and span more than one line. Replace these calls
with a wrapper macros for RX/Tx compls and TX wrb. This results in fewer
lines and more readable code in be_main.c

Subject: be2net: fix log messages in lancer FW download path

Log messages in the Lancer FW download path have issues such as:
- a single message spanning multiple lines
- the success message is logged even in failure cases
- status codes are already logged in the FW cmd routines
This patch fixes these issues.

There are a few failure cases in be_cmd_get_regs() that ideally must return
an error value. This style is used across all the routines in be_cmds.c with
this routine being an exception. This patch fixes this.

Subject: be2net: define macro for_all_tx_queues_on_eq()

Replace the for() loop that traverses all the TX queues on an EQ
with the macro for_all_tx_queues_on_eq(). With this expalnatory
name, the one line comment is not required anymore.

Subject: be2net: query max_tx_qs for BE3 super-nic profile from FW

In the BE3 super-nic profile, the max_tx_qs value can vary for each function.
So the driver needs to query this value from FW instead of using the
pre-defined constant BE3_MAX_TX_QS.
