Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.
Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory
space independently.

When booting shim -> fallback -> shim -> grub -> linux the memory map is
a bit larger than the size linux passes in on the first call. But in
the EFI_BUFFER_TOO_SMALL case we were not passing back the updated size
to linux so it would loop forever.

The first argument 'type' of CreateEvent is an 32bit unsigned
integer bitmap and not an enum.
The second argument 'type' of SetTimer take values of an
enum which is called EFI_TIMER_DELAY in the UEFI standard.
To avoid confusion rename efi_event_type to efi_timer_delay.

In efi_set_timer we receive the trigger time in intervals of 100 ns.

The efi_loader currently stops iterating over the available
block devices stopping at the first device that fails.
This may imply that no block device is found.
With the patch efi_loader only iterates over valid devices.
It is based on patch
06d592bf52f6 (dm: core: Add uclass_first/next_device_check())
which is currently in u-boot-dm.git.
For testing I used an odroid-c2 with a dts including
&sd_emmc_a {
status = "okay";
};
This device does not exist on the board and cannot be initialized.
Without the patch:

WARNING: Invalid device tree, expect boot to fail
mmc_init: -95, time 1806

efi_open_protocol was implemented to call a protocol specific open

UEFI spec 2.7 indicates that HandleProtocol can be implemented
by calling OpenProtocol with
attributes = EFI_OPEN_PROTOCOL_BY_HANDLE_PROTOCOL.
Currently we pass attributes = 0 to efi_open_protocol. 0 is not a
valid value when calling OpenProtocol. This does not cause any errors
yet because our implementation of OpenProtocol is incomplete.
We should pass the correct value to enable a fully compliant
implementation of OpenProtocol in the future.
