The new chip series has 64 bit doorbell for notification queues. Thus,
both control and data path event queues need new routines to write 64 bit
doorbell. Adding the same. There is new doorbell interface between the
chip and driver. Changing the chip specific data structure definitions.
Additional significant changes are listed below
- bnxt_re_net_ring_free/alloc takes a new argument
- bnxt_qplib_enable_nq and enable_rcfw uses new doorbell offset
for new chip.
- DB mapping for NQ and CREQ now maps 8 bytes.
- DBR_DBR_* macros renames to DBC_DBC_*
- store nq_db_offset in a 32bit data type.
- got rid of __iowrite64_copy, used writeq instead.
- changed the DB header initialization to simpler scheme.

bnxt_en depends on MAY_USE_DEVLINK; this is used to force bnxt_en
to be =m when DEVLINK is =m.
Now, bnxt_re selects bnxt_en. Unless bnxt_re also explicitly calls
out dependency on MAY_USE_DEVLINK, Kconfig does not force bnxt_re
to be =m when DEVLINK is =m, causing the following error:
drivers/net/ethernet/broadcom/bnxt/bnxt_vfr.o: In function
`bnxt_dl_register':
bnxt_vfr.c:(.text+0x1440): undefined reference to `devlink_alloc'
bnxt_vfr.c:(.text+0x14c0): undefined reference to `devlink_register'
bnxt_vfr.c:(.text+0x14e0): undefined reference to `devlink_free'

bnxt_vfr.c:(.text+0x1534): undefined reference to `devlink_unregister'
bnxt_vfr.c:(.text+0x153c): undefined reference to `devlink_free'
Fix this by adding MAY_USE_DEVLINK dependency in bnxt_re.

When CONFIG_DCB is disabled, we get a link error:
drivers/infiniband/built-in.o: In function `bnxt_re_setup_qos':
trace.c:(.text+0x155774): undefined reference to `dcb_ieee_getapp_mask'
trace.c:(.text+0x155774): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dcb_ieee_getapp_mask'

trace.c:(.text+0x155794): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dcb_ieee_getapp_mask'
Like the other drivers that use this function, a Kconfig dependency is
the correct fix.
