Write to the PWREN register should be done in update_ios based
on the power_mode value in the ios struct.
Also none of the manual (RockChip and Altera) and Linux talks about
the needed for an inverted PWREN value so just remove this.
This fixes eMMC (and possibly SD) when u-boot didn't setup the controller.

Extend the size of the local rx_buffer_size variable to account for
larger buffer sizes possible on 82580, i350 chips.
From i350 datasheet, 6.2.10 Initialization Control 4 (LAN Base Address
+ Offset 0x13):
When 4 ports are enabled maximum buffer size is 36 KB. When 2 ports are
enabled maximum buffer size is 72 KB. When only a single port is
enabled maximum buffer size is 144 KB.
and 8.3:
The overall available internal buffer size in the I350 for all ports is
144 KB for receive buffers and 80 KB for transmit Buffers. Disabled
ports memory can be shared between active ports and sharing can be
asymmetric. The default buffer size for each port is loaded from the
EEPROM on initialization.
From the reporter:
But for I350 when only 2 ports are used PBA size can be set as 72KB
(see datasheet RXPbsize or e1000_rxpbs_adjust_82580 function in
e1000_82575.c). In this case calculating the rx_buffer_size overflows
as 0x0048 << 10 = 73728 or 0x12000 pushed into u16. It is then set as
0x2000 or 8192.

- Add icl_pdu_append_bio and icl_pdu_get_bio methods.
- Add new page pod routines for allocating and writing page pods for
unmapped bio requests. Use these new routines for setting up DDP
for iSCSI tasks with a SCSI I/O CCB which uses CAM_DATA_BIO.
- When ICL_NOCOPY is used to append data from an unmapped I/O request
to a PDU, construct unmapped mbufs from the relevant pages backing
the struct bio. This also requires changes in the t4_push_pdus path
to support unmapped mbufs.

Don't assume that csio->data_ptr is pointer to a data buffer that can
be passed to icl_get_pdu_data and icl_append_data. For unmapped I/O
requests, csio->data_ptr is instead a pointer to a struct bio as
indicated by CAM_DATA_BIO. To support these requests, add
icl_pdu_append_bio and icl_pdu_get_bio methods which pass a pointer to
the bio and an offset and length relative to the bio's buffer.
Note that only backends supporting unmapped requests need to implement
these hooks.
Implement simple no-op hooks for the iser backend.

The associated csio ccb will not be completed via xpt_done() until
after the associated PDUs are transmitted to the other side and either
the original PDU is acked with a SCSI response, or a response is
received for a subsequent abort CCB (which means the earlier PDU has
also been sent since it would have been sent before the abort PDU).
This does assume that once an I/O request has been aborted, no further
PDUs with data payload are queued for that I/O request.

struct sglist is intended for holding S/G lists of physical address
ranges, not virtual address ranges. GCC 9.x issues several warnings
due to casts between pointers and integers of different sizes as a
result (vm_paddr_t is 64-bits on i386). Instead, add a local 'struct
hv_sglist' which uses an array of 'struct iovec' to hold the S/G list
of virtual address ranges.

Previously the driver was called to send PDUs to the NIC synchronously
from the icl_conn_pdu_queue_cb callback. However, this performed a
fair bit of work while holding the icl connection lock. Instead,
change the callback to add sent PDUs to a STAILQ and defer dispatching
of PDUs to the NIC to a helper thread similar to the scheme used in
the TCP iSCSI backend.
