Subtle ARC fixes for v2018.05-RC3

These are only very subtle clean-ups here and there including:

 * Correctly specified CPU freq for HSDK
   (production boards are all shipped with 500MHZ as opposed
    to early batch running at 1GHz)

 * Addition of SNPS internal group email to MAINTAINERS file
 * Switch to Hush shell on AXS10x boards

In the commit "reset: Add get/assert/deassert/release for bulk of reset signals"
the disabled reset_release_bulk() and reset_get_bulk() used the wrong
struct clk_bulk instead of struct reset_ctl_bulk.

commit b4d956f6 ("bootm: Align cache flush end address correctly")
aligns the end address of the cache flush operation to a cache-line size to
ensure lower-layers in the code accept the range provided and flush.

A similar action should be taken for the begin address of a cache flush
operation. The load address may not be aligned to a cache-line boundary, so
ensure the passed address is aligned.

None of the SoCFPGA platforms will support EFI/ISO partition types that
is needed for DISTRO_DEFAULTS. SoCFPGA bootroom will only support 0xa2
partition type.

This is needed to help limit the size of the SPL to within the 64k limit
that is required for SoCFPGA.

Add code to look for a reset manager property. Specifically, look for the
reset-names of 'i2c'. A reset property is an optional feature, so only print
out a warning and do not fail if a reset property is not present.

If a reset property is discovered, then use it to deassert, thus bringing the
IP out of reset.

Since commit 8e14ba7b ("gpio: omap_gpio: Add DM_FLAG_PRE_RELOC
flag") omap GPIO gets bound before relocation.  Unfortunately due to
this, on at least the beaglebone black, the pre-relocation memory pool
gets exhausted before probing the serial port. This then causes u-boot
to panic as CONFIG_REQUIRE_SERIAL_CONSOLE is set...

Resolve this by resizing the default size of the pre-relocation malloc
pool for AM335X platforms.

We enabled CONFIG_ISO_PARTITION by default for distro boot, so that U-Boot
could load distro images that usually get shipped as iso images. These images
usually come with a board agnostic boot environment.

However, there is very little point in having ISO support enabled (for anyone
really) in SPL, as the whole idea of SPL is to load U-Boot proper which again
is board specific. So the fact that we enable ISO support in U-Boot proper does
not mean at all that we want ISO support in U-Boot SPL.

Hence, let's remove the Kconfig dependency. Along the way, let's also clean up
all those default configs that disabled SPL ISO support.
