soc/cores/gpio: Simplify GPIOIn IRQ, make polarity configurable and also add optional IRQ to GPIOTristate.
...
Ex of instance:
from litex.soc.cores import gpio
gpio_in_pads = Signal(16)
self.submodules.gpio_in = gpio.GPIOIn(gpio_in_pads, with_irq=True)
self.add_csr("gpio_in")

bios: Add boot command to be able to boot directly from system memory.
...
This is useful for un-usual boot sequences where the binaries are not
loaded directly by the BIOS but externally (over a bridge for example).
Example of use:
$litex_sim
$litex_bare_metal_demo --build-path=build/sim
$litex_sim --ram-init=demo.bin
Press Esc during the LiteX boot.
