scripts/spelling.txt: add "aligment" pattern and fix typo instances

Fix typos and add the following to the scripts/spelling.txt:

aligment||alignment

I did not touch the "N_BYTE_ALIGMENT" macro in
drivers/net/wireless/realtek/rtlwifi/wifi.h to avoid unpredictable
impact.

I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because
it is surrounded by #if 0 ... #endif. It is surely safe and I
confirmed "_alignment_handler" is correct.

I also fixed the "controler" I found in the same hunk in
arch/openrisc/kernel/head.S.

[SCSI] bfa: Add support for FC Arbitrated Loop topology.

- Add private loop topology support at 2G/4G/8G speeds with following
limitations
1. No support for multiple initiators in the loop
2. No public loop support. If attached to a loop with an FL_Port,
device continues to work as a private NL_Port in the loop
3. No auto topology detection. User has to manually set the
configured topology to loop if attaching to loop.
- When loop topology is configured, enabling FC port features
QoS/Trunk/TRL are not allowed and vice versa.

[SCSI] bfa: DMA memory allocation enhancement.

- Modified the design such that each BFA sub-module will provide
the amount of DMA and KVA memory needed by it and queues the
same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
needed by all the BFA sub-modules as one contiguous chunk.

[SCSI] bfa: Brocade-1860 Fabric Adapter vHBA support.

- Introduced partitioning of the BFA resources.
- Added h/w queue ID in CPE messages, firmware uses h/w queue ID
from messages to pick a matching RME queue.
- Added message header to bfa_reqq_produce(). h/w queue ID is set
in the message header and firmware modules use h/w queue ID from
message header instead of from cpqe event.
- Made changes to allow using all 256 queues of Brocade-1860 asic.
Previously only a single queue per queue group was used.
- Added function tag to BFI message header. Only used by FC BFI
messages. Used to translate host tag to firmware tag. bfa_lpuid()
is changed to bfa_fn_lpu() that encodes both PCI function and port
ID in BFI message header.

[SCSI] bfa: Brocade-1860 Fabric Adapter PLL init fixes.

- If flash controller is halted unconditionally, this results in
illegal write access to flash controller register domain. Since
flash controller registers are only accessible once s_clk is started
- added logic to check for WGN status and halt flash controller only
if it is already running.
- Added check to wait for flash controller halt to be completed before
proceeding with s_clk/l_clk initializations.
- Removed unnecessary reset logic for PMM 1T memory and moved memory
initialization after flash access enable.
- Disable Brocade-1860 asic MBOX interrupt before PLL initialization.
- Remove reset enable for S_CLK/L_CLK after both PLL initializations
are complete.

[SCSI] bfa: FC credit recovery and misc bug fixes.

- Introduce FC credit recovery.
- Added module parameter to enable/disable credit recovery.

Bug Fixes:
- Removed check for ignoring plogi from initiator in switched fabric mode.
- The ABTS for PLOGI is going out few millisecs earlier due to FW
timer calibration (around 300 miilisecs earlier). So there is a
window if an accept comes during this time HBA would have initiated
an ABORT.
- Added 1 to FC_ELS_TOV for compensating for FW timer.

[SCSI] bfa: Store port configuration in flash for persistency.

When the bfa driver is loaded a flogi is sent without the knowledge of
trunking configuration. This normal flogi causes the switch ports
which had trunking enabled to go to persistent offline. Solution is
to store the port configuration (which has trunking info) in the flash
for persistency. The firmware will read this configuration when the
very first fcport enable is received.
