acpi: EJ0 method name patching
Modify ACPI to only supply _EJ0 methods for PCI slots that support hotplug.
This is done by runtime patching:
- Instrument SSDT ASL code with ACPI_EXTRACT directives
tagging _EJ0 and _ADR fields.
- At compile time, tools/acpi_extract.py looks for these methods
in ASL source finds the matching AML, and stores the offsets
of these methods in tables named aml_ej0_name and aml_adr_dword.
- At run time, go over aml_ej0_name, use aml_adr_dword
to get slot information and check which slots support hotplug.
If hotplug is disabled, we patch the _EJ0 NameString in ACPI table,
replacing _EJ0 with EJ0_.
Note that this has the same checksum, but is ignored by OSPM.
Note: the method used is robust in that we don't need
to change any offsets manually in case of ASL code changes.
As all parsing is done at compile time, any unexpected input causes
build failure, not a runtime failure.

usb-uhci: fix race against host controller
While processing a frame, the host controller will write to the queue
head's element link field. The following sequence could then happen

controller SeaBIOS
---------------------------------------------------------------------
td->link = UHCI_PTR_TERM;
td->ctrl |= TD_CTRL_ACTIVE;
read TD from memory
wait_td(td);
td->ctrl &= ~TD_CTRL_ACTIVE;

pipe->qh.element = td->link; ... go on and set up the first td ...
write back pipe->qh.element
td->ctrl |= TD_CTRL_ACTIVE;
Once the host controller has written UHCI_PTR_TERM to the element link,
subsequent tds would never be processed. This is surprisingly frequent
when the two consecutive sends are in the OUT direction (and just as
surprisingly, it seems like it never happens in the IN direction).
To fix this, at the end of the processing do not wait for each single
TD to become inactive, but for the host controller to invalidate the
element link (which implies it's done with all TDs).

Some versions of gcc have difficulties with externally visible
variables that are used before they are declared. Now that pmm.c
contains only 32bit code and has a reference to CanPreempt, make sure
the declaration of CanPreempt (in stacks.c) is compiled first.

Define handle_post as VISIBLE32FLAT as work around for QEmu memory layout.
QEmu only copies the top 128K of the BIOS image to low memory
(0xe0000-0xfffff). Images over 128K are only fully mapped in high
memory (0xfff00000). However, the SeaBIOS shadow functions
(make_bios_writable_intel) will copy up to 256K to low memory.
SeaBIOS generally works with 256K roms because they are automatically
copied to low memory during the BIOS init. However, this only works
if the shadow function code is itself part of the bios image that is
placed in low memory by QEmu.
Defining handle_post() as VISIBLE32FLAT will make the linker scripts
more likely to place the initial shadow code in the last 128K of the
image.

Rework init workflow to match suggestions in the ahci specs better,
especially remove the shortcut which tries to detect drives without
enabling FIS receiving. This makes memory allocation a bit complicated
as we are using malloc_tmp() allocated memory now to probe the devices
so we can free it when no drive is present. In case we detect a drive
we have to free and realloc the memory with malloc_low() so it is
available after POST when the boot loader wants read stuff via int13.
Also use TSC to calculate timeout instead of delays and loop counts.
