Because of some board issues, we need to disable parallel detect on
an HP blade. Without this patch, the link state can become stuck
when it goes into parallel detect mode.

The REG_WR_IND/REG_RD_IND macros are unnecessary and obfuscate the
code. Many callers to these macros read and write shared memory from
the bp->shmem_base, so we add 2 similar functions that automatically
add the shared memory base.

In some blade systems using the 5706 serdes, the hardware sometimes
does not properly generate link down interrupts. We add a workaround
in the driver's timer to force a link-down when some PHY registers
report loss of SYNC.
The parallel detect logic is cleaned up slightly to better integrate
the workaround.

Introduce a bnx2_napi structure that will hold a napi_struct and
other fields to handle NAPI polling for the napi_struct. Various tx
and rx indexes and status block pointers will be moved from the main
bnx2 structure to this bnx2_napi structure.
Most NAPI path functions are modified to be passed this bnx2_napi
struct pointer.

Packets can be left in the RX ring if the NAPI budget is reached.
This is caused by storing the latest rx index at the beginning of
bnx2_rx_int(). We may not process all the work up to this index
if the budget is reached and so some packets in the RX ring may rot
when we later check for more work using this stored rx index.
The fix is to not store this latest hw index and only store the
processed rx index. We use a new function bnx2_get_hw_rx_cons()
to fetch the latest hw rx index.

This is a follow up to the patches from Denys Vlasenkos
<vda.linux@googlemail.com> to further optimize firmware loading.
1. In bnx2_init_cpus(), we allocate memory for decompression once
and use it repeatedly instead of doing this for every firmware image.
2. We eliminate the BSS and SBSS firmware sections in bnx2_fw*.h since
these are always zeros.
