b0eaf97404 Add subclass of simplebus for Broadcom XLP
This will override the resource allocation of simplebus, and also
merge the resource allocation code which was in xlp_pci.c.

With this change the SoC devices that does not have proper PCI
resources will be on the FDT simplebus. We can remove
sys/mips/nlm/dev/cfi_pci_xlp.c and sys/mips/nlm/dev/uart_pci_xlp.c

ba32078fbc Move PCI bus below simplebus for Broadcom XLP

1f4069c7a5 Improve additional interrupt ACK for Broadcom XLP
Handling some interrupts in XLP (like PCIe and SATA) involves writing to
vendor specific registers as part of interrupt acknowledgement.

This was earlier done with xlp_establish_intr(), but a better solution
is to provide a function xlp_set_bus_ack() that can be used with
cpu_establish_hardintr(). This will allow platform initialization code to
setup these ACKs without changing the standrard drivers.

e88bd26b3f Follow up to r225617. In order to maximize the re-usability of kernel code
in userland rename in-kernel getenv()/setenv() to kern_setenv()/kern_getenv().
This fixes a namespace collision with libc symbols.

44c01df173 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

b243ad67b9 Little-endian and other fixes for Broadcom XLP network driver
The changes are:
 - the microcore code loaded into the NAE has to be byteswapped
   in LE
 - the descriptors in memory for a P2P NAE descriptor has to be
   byteswapped in LE
 - the m_data pointer is already cacheline aligned, so the
   unnecessary m_adj to cacheline size can be removed
 - fix mask used to obtain physical address from the Tx freeback
   descriptor
 - fix a compile error in code under #ifdef

0ec682f566 Update memory and resource allocation code for SoC devices
The XLP on-chip devices have PCI configuration headers, but some of the
devices need custom resource allocation code.
- devices with no MEM/IO BARs with registers in PCIe extended reg
  space have to be handled in memory resource allocation
- devices without INTPIN/INTLINE in PCI header can be supported
  by having these faked with a shadow register.
- Some devices does not allow 8/16 bit access to the register space,
  he default bus space cannot be used for these.

Subclass pci and override attach and resource allocation methods to
take care of this.

Remove earlier code which did this partially.

ac2071063e Remove platform APIs which are not used by any code and which had only stub

Some of these functions might be good ideas, but their semantics were unclear
given the lack of implementation, and an unlucky porter could be fooled into
trying to implement them or, worse, being baffled when something like
platform_trap_enter() failed to be called.
