BCM6328 has a OTP which tells us if the second core is available.

This involves two changes to the BSP code:

1) register_smp_ops() for BMIPS SMP

2) The CPU1 boot vector on some of the BCM63xx platforms conflicts with
the special interrupt vector (IV).  Move it to 0x8000_0380 at boot time,
to resolve the conflict.

[jogo@openwrt.org: moved SMP ops registration into ifdef guard,
 changed ifdef guards to if (IS_ENABLED())]

The Broadcom BCM3368 Cable Modem SoC is extremely similar to the
existing BCM63xx DSL SoCs, in particular BCM6358, therefore little effort
in the existing code base is required to get it supported. This patch adds
support for the following on-chip peripherals:

- two UARTS
- GPIO
- Ethernet
- SPI
- PCI
- NOR Flash

The most noticeable difference with 3368 is that it has its peripheral
register at 0xfff8_0000 we check that separately in ioremap.h. Since
3368 is identical to 6358 for its clock and reset bits, we use them
verbatim.

This includes CPU speed, memory size detection and working UART, but
lacking the appropriate drivers, no support for attached flash.
