Revert "bcma: init serial console directly from ChipCommon code"

This reverts commit 4c81acab3816 ("bcma: init serial console directly
from ChipCommon code") as it broke IRQ assignment. Getting IRQ with
bcma_core_irq helper on SoC requires MIPS core to be set. It happens
*after* ChipCommon initialization so we can't do this so early.

This fixes a user reported regression. It wasn't critical as serial was
still somehow working but lack of IRQs was making in unreliable.

bcma: support BCM53573 series of wireless SoCs

BCM53573 seems to be the first series of Northstar family with wireless
on the chip. The base models are BCM53573-s (A0, A1) and there is also
BCM47189B0 which seems to be some small modification.

The only problem with these chipsets seems to be watchdog. It's totally
unavailable on 53573A0 / 53573A1 and preferable PMU watchdog is broken
on 53573B0 / 53573B1.

bcma: move flash detection code to ChipCommon core driver

Flashes are attached and accessible through ChipCommon core, they aren't
connected to MIPS one. Moreover some new ARM devices (e.g. BCM47189) may
have serial flash accessibility using ChipCommon registers as well. To
support them we can't keep this code in MIPS core driver.

bcma: init serial console directly from ChipCommon code

UART is connected to and controlled over ChipCommon core. It doesn't

except just existing on embedded systemms. There isn't point of such
cross-core initialization (and we needed #ifdef anyway) so just handle
it in ChipCommon.

Solve it by using a new (PMU) core pointer set to ChipCommon or PMU
depending on the hardware capabilities.
