This adds some missing IOMMU related options for x86/64 and moves some
of them to generic for all targets.
On x86 IOMMU_DEFAULT_DMA_LAZY is used by default, on all other platforms
IOMMU_DEFAULT_DMA_STRICT is the default. we just follow the default
kernel configuration here.

All targets expect the malta target already activate the CONFIG_GPIOLIB
option. Move it to generic kernel configuration and also activate it for
malta.

Enable PowerPC Book-E Watchdog Timer support. Having this enabled
in-kernel will result in procd starting it during boot.
This effectively solves the problem of the WDT in the Winbond W83793 chip
potentially resetting the system during sysupgrade, which could result
in an unbootable device. While the driver is modular, resulting in procd
not starting the WDT during boot (because that happens before kmod
load), the WDT handover during sysupgrade results in the WDT being
started. This normally shouldn't be a problem, but the W83793 WDT does
not like procd's defaults, nor the handover happening during sysupgrade.

The WatchGuard Firebox M200 and M300 use a Marvell 88e1543 PHY for the
first 3 ethernet ports. This PHY is supported by the Marvell Alaska PHY
driver, so enable it.

It is disabled in the generic kernel config and not used in any of the
other targets. There was no specific reason for enabling it, so let's be
consistent and remove it from the qoriq kernel config.

The I2C controller used in QorIQ PPC devices requires the mpc-i2c
driver, which is enabled by the I2C_MPC kernel config symbol. Enable
this and its dependencies in the target kernel config, as is done for
the mpc85xx target.
This fixes missing hwmon, rtc and tpm devices on the M300.

Add a new target named "qoriq", that will support boards using PowerPC
processors from NXP's QorIQ brand.
This doesn't actually add support for any board yet, so that
installation instructions can go in the commit message of the commit
that adds actual support for a board.
Using CONFIG_E6500_CPU here due to the kernel using -mcpu=powerpc64
rather than -mcpu=e5500 when selecting CONFIG_E5500_CPU. The only
difference between e5500 and e6500 is AltiVec support, and the kernel
checks for it at runtime. Musl will only check at runtime if AltiVec
support is disabled at compile-time, so we need to use e5500 in CPU_TYPE
to avoid SIGILL.
Math emulation (CONFIG_MATH_EMULATION_HW_UNIMPLEMENTED) is required, as
neither e5500 nor e6500 implement fsqrt nor fsqrts, and musl hardcodes
sqrt and sqrtf to use these ASM instructions on PowerPC64.
