xen/arm: Implement a virtual UART
This code is based on the previous vuart0 implementation. Unlike the latter,
it''s intend to replace UART stolen by XEN to DOM0 via dtuart=... on
its
command line.
It''s useful when the kernel is compiled with early printk enabled
or for a
single platform. Most of the time, the hardcoded code to handle the UART
will need 2 registers: status and data, the others registers can be
implemented as RAZ/WI.
This commit will also drop support of early printk (based on vexpress pl011)
in the guest.

rombios/ata Remove another needless trap from the int 0x13 hotpath
The return value from await_ide() is always ignored, and most calls to
await_ide() immediately reread the status register.
Therefore, making await_ide() return the last value of the status register
removes a further two traps on the int 0x13 path.

rombios/ata: Do not wait for BSY to be set
After issuing a reset, the BSY bit is expected to be set. This is not the
case for Qemu.
In SeaBIOS.git: 580e33293244fee4556e56ecc67b8bd877f3c496
this check was even replaced with a udelay(5), as enough real hardware
ignored
the BSY bit as well.
As rombios does not have an equivalent udelay(), replace the wait with a
write
to port 0x80 which is whitelisted by Xen for ''a small
delay''.
This causes 42k fewer IO traps to Qemu.

The p2mt change check for p2m_change_type() was first introduced when

protected by p2m_lock. So p2mt should never change before

The requested vector count is to be passed in struct xen_pci_op''s

This implies
- extending the public interface to have a way to request a block of

- allocating a block of contiguous pIRQ-s for the target domain (but
note that the Xen IRQs allocated have no need of being contiguous)
- repeating certain operations for all involved IRQs
- fixing multi_msi_enable()
- adjusting the mask bit accesses for maskable MSIs
