This patch adds a "bulk" API to the phy API in order to
get/init/exit/power on/off a group of phys associated
with a device.
The bulk API will avoid adding a copy of the same code to
manage a group of phys in drivers.

As noted in rtc_def.h, the tm_mon field in struct rtc_time is 1-12,
unlike in struct tm where it is 0-11. Currently, running "date" prints
the wrong
Date: 2020-04-01 (Friday) Time: 13:05:30
and setting the RTC via the date command is also broken.

Inline all the functions from the header file, as they are not used
outside of the driver or the standalone EEPROM example.
Note that this does introduce considerable amount of duplication in
the standalone EEPROM example, however that one has to be rewritten
anyway, roughly such that the SMC911x driver would expose DM EEPROM
interface and the standalone example would use that.

The rtl8139 driver is derived from Etherboot driver, which is in
turn derived from Linux 8139too driver added in Linux 2.2.18pre14.
An undocumented change in Linux 2.4.10.2 added a new field to the
driver, MODULE_LICENSE("GPL"); . According to current Linux kernel
licensing rules, Documentation/process/license-rules.rst, quote:
"GPL" Module is licensed under GPL version 2. This
does not express any distinction between
GPL-2.0-only or GPL-2.0-or-later. The exact
license information can only be determined
via the license information in the
corresponding source files.
And since the code does not contain any "future" clause, the tag
is therefore GPL-2.0 only.

This hardware reset and reset-wait implementation was twice in the

The DMA may attempt to write a DMA descriptor in the ring while it is
being updated. By writing the DMA descriptor buffer address to 0, it
is assured the DMA will not use such a buffer and the buffer can be
updated without any interference.

This patch prevents an issue where the RX packet might have been
accessed by the CPU, which now has cached data from the packet in
the caches and possibly various write buffers, and these data may
be evicted from the caches into the DRAM while the buffer is also
written by the DMA.
By invalidating the buffer after the CPU accessed it and before the
DMA populates the buffer, it is assured that the buffer will not be
corrupted.

The current code polls the RX desciptor ring for new packets by reading
the RX descriptor status. This works by accident, as the RX descriptors
are often in non-cacheable memory. However, the driver does support use
of RX descriptors in cacheable memory.
This patch adds a missing RX descriptor invalidation, which assures the
CPU will read a fresh copy of the RX descriptor instead of a cached one.

This code programs the next descriptor in the TX descriptor ring into
the hardware as the last valid TX descriptor. The problem is that if
the currenty descriptor is the last one in the array, the code will
not wrap around correctly and use TX descriptor 0 again, but instead
will use TX descriptor at address right past the TX descriptor ring,
which is the first descriptor in the RX ring.
Fix this by adding the necessary wrap-around.

The RX descriptor field 3 should contain only OWN and BUF1V bits before
being used for receiving data by the DMA engine. However, right now, if
the descriptor was already used for receiving data and is being cleared,
the field 3 is only modified and the aforementioned two bits are ORRed
into the field. This could lead to a residual dirty bits being left in
the field 3 from previous transfer, and it generally does. Fully set the
field 3 instead to clear those residual dirty bits.
