Currently, the SDM845 configuration data defines resource limits for
the first two resource groups (for both source and destination
resource types).  The hardware supports additional resource groups,
and we should program the resource limits for those groups as well.

Even the "unused" destination resource group (number 2) should have
non-zero limits programmed in some cases, to ensure correct operation.

Add these missing resource group limit definitions to the SDM845
configuration data.

Define a new ipa_resource_group_id enumerated type, whose members
have numeric values that match the resource group number used when
programming the hardware.  Each platform supports a different number
of source and destination resource groups, so define the type
separately for each platform in its configuration data file.

Use these new symbolic values when specifying the resource group an
endpoint is associated with.  And use them to index the limits
arrays for source and destination resources, making it clearer how
these values are used.

If the number of resource groups supported by the hardware is less
than a certain number, we return early in ipa_resource_config_src()
and ipa_resource_config_dst() (to avoid programming resource limits
for non-existent groups).

Unfortunately, these checks are off by one.  Fix this problem in the
four places it occurs.

net: stmmac: enable multi-vector MSI

This patchset adds support for multi MSI interrupts in addition to
current single common interrupt implementation. Each MSI interrupt is tied
to a newly introduce interrupt service routine(ISR). Hence, each interrupt
will only go through the corresponding ISR.

In order to increase the efficiency, enabling multi MSI interrupt will
automatically select the interrupt mode configuration INTM=1. When INTM=1,
the TX/RX transfer complete signal will only asserted on corresponding
sbd_perch_tx_intr_o[] or sbd_perch_rx_intr_o[] without asserting signal
on the common sbd_intr_o. Hence, for each TX/RX interrupts, only the
corresponding ISR will be triggered.

Every vendor might have different MSI vector assignment. So, this patchset
only includes multi-vector MSI assignment for Intel platform.

Changes:
v1 -> v2
 patch 2/5
 -Remove defensive check for invalid dev pointer
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

For interrupt mode INTM=0, TX/RX transfer complete will trigger signal
not only on sbd_perch_[tx|rx]_intr_o (Transmit/Receive Per Channel) but
also on the sbd_intr_o (Common).

As for multi-MSI implementation, setting interrupt mode INTM=1 is more
efficient as each TX intr and RX intr (TI/RI) will be handled by TX/RX ISR
without the need of calling the common MAC ISR.

Updated the TX/RX NORMAL interrupts status checking process as the
NIS status bit is not asserted for any RI/TI events for INTM=1.
