Fix EMAC soft reset on 460EX/GT to select the right PHY clock source
before and after the soft reset.

EMAC with PHY should use the clock from PHY during soft reset.
EMAC without PHY should use the internal clock during soft reset.

PPC460EX/GT Embedded Processor Advanced User's Manual
section 28.10.1 Mode Register 0 (EMACx_MR0) states:
Note: The PHY must provide a TX Clk in order to perform a soft reset
of the EMAC. If none is present, select the internal clock
(SDR0_ETH_CFG[EMACx_PHY_CLK] = 1).
After a soft reset, select the external clock.

Without the fix, 460EX/GT-based boards with RGMII PHYs attached to
EMACs experience EMAC interrupt storm and system watchdog reset when
issuing "ifconfig eth0 down" + "ifconfig eth0 up" a few times.
The system enters endless loop of serving emac_irq() with EMACx_ISR
register stuck at value 0x10000000 (Rx parity error).

With the fix, the above issue is no longer observed.

In commit 9aa32835 (ehea/ibm*: Move the
IBM drivers) the IBM_NEW_EMAC* were renames to IBM_EMAC*

The conversion was incomplete so that even if the driver was added to
the .config it wasn't built, but there were no errors).  In this commit
we also update the various defconfigs that use EMAC to use the new
Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard.

We do not explicitly select the Kconfig dependencies, as this would force
EMAC on.  Doing it in the defconfig allows more flexibility.

flush_scheduled_work() is on its way out.  This patch contains simple
conversions to replace flush_scheduled_work() usage with direct
cancels and flushes.

Directly cancel the used works on driver detach and flush them in
other cases.

The conversions are mostly straight forward and the only dangers are,

* Forgetting to cancel/flush one or more used works.

* Cancelling when a work should be flushed (ie. the work must be
  executed once scheduled whether the driver is detaching or not).

I've gone over the changes multiple times but it would be much
appreciated if you can review with the above points in mind.
