argc = 1: all tests are run
argc > 1: only argv[1] is run

So we need argc >= 1.

Now that we have full Linux kernel boot support on EFI payload,
avoid pass "acpi=off" to the kernel command line.

At present Linux kernel loaded from U-Boot as an EFI payload does
not boot. This fills in kernel's boot params structure with the
required critical EFI information like system table address and
memory map stuff so that kernel can obtain essential data like
runtime services and ACPI table to boot.

With this patch, now U-Boot as an EFI payload becomes much more
practical: it is another option of kernel bootloader, ie, can be
a replacement for grub.

This updates the EFI stub codes to pass UEFI BIOS's system table
address to U-Boot payload so that U-Boot can utilize it.

Copy missing Kernel patch to make SLEWCTRL_SLOW available in device tree
and to correct the value of SLEWCTRL_FAST.
After this patch, the Kernel and U-boot device tree settings for
SLEWCTRL have the same effect.

Original Kernel patch message:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=424e0f039bfa8a51fb5c5178b6ece8baa4996469

According to AM335x TRM, Document spruh73l, Revised February 2015,
Section 9.2.2 Pad Control Registers, setting bit 6 of the pad control
registers actually sets the SLEWCTRL value to slow rather than fast as
the current macro indicates. Introduce a new macro, SLEWCTRL_SLOW, that
sets the bit, and modify SLEWCTRL_FAST to 0 but keep it for
completeness. Current users of the macro (i2c and mdio) are left
unmodified as SLEWCTRL_FAST was the macro used and actual desired state.
Tested on am335x-gp-evm with no difference in software performance seen.
