RCC device could be common to various STM32 series.
Until now, PLL handling code was set in series specific files,
even if it was driving the same device than another series.
Minimize code duplication by factorizing code between series
when possible.
With this change, some series get additional features by getting
access to code developed for other series.
Additionally, while renaming the files, remove the non informative
'x' to minimize file name length

More clearly differentiate MVIC vs. APIC timer code, and use new APIC
accessors in include/drivers/loapic.h. Remove extraneous comments, and
other light cleanup work.
This driver is in need of a serious overhaul -- despite appearing to
have support for TICKLESS_KERNEL and DEVICE_POWER_MANAGEMENT, bitrot
has taken its toll and the driver will not build with these enabled.
These should be removed or made to work... but not in this patch.
Old x2APIC-related accessors in kernel_arch_func.h are eliminated.

drivers/interrupt_controller/i8259.c is not a driver; it exists
solely to disable the i8259s when the configuration calls for it.
The six-byte sequence to mask the controllers is moved to crt0.S

A basic display driver is added for a generic 32-bpp framebuffer.
Glue logic is added to the x86 arch to request the intitialization
of a linear framebuffer by the Multiboot loader (GRUB) and connect
it to this generic driver.

It does make sense to initialize USB console after USB Device stack.
Note that the value is selected only if we specify USB_UART_CONSOLE

Basically, all driver file names should start with the driver type as
prefix: wdt_ in case of watchdogs here, and not something custom like
wdog_.
For clarity, wdog_ prefix could be changed to wdt_ in the source code
also but that's a detail and will not be addressed here.

Some firmwares (looking at you, slimbootloader) don't set the registers
in PCI configuration space to indicate the IRQ routing, so we remove
the check that verifies that the user and firmware agree on IRQ number.
Also eliminate the return value of pcie_irq_enable() since no one uses
it and we can't return a meaningful value any longer.

Implement the get_status DMA API for the SAM0 DMA controller.
The busy field is set only when the selected channel is
actively transferring data (i.e. both enabled and selected by the
arbiter). The direction field is left unset, since that
information is not normally retained by the DMA controller.

ESP32 can sport up to 4 network interfaces: two 802.11 (station and
ap), ethernet, and bluetooth. All of them derive from the same RDATA
register in efuse block 0. However, in most cases, the last (sixth)
octet will change like so:
- 802.11 station: mac[5] += 0
- 802.11 ap: mac[5] += 1
- bluetooth: mac[5] += 2
- ethernet: mac[5] += 3
