drivers: add emmc stack

In a lot of embedded platforms, eMMC device is the only one storage
device. So loading content from eMMC device is required in ATF.

Create the emmc stack that could co-work with IO block driver.
Support to read/write/erase eMMC blocks on both rpmb and normal
user area. Support to change the IO speed and bus width.

IO: support block device type

FIP is accessed as memory-mapped type. eMMC is block device type.
In order to support FIP based on eMMC, add the new io_block layer.

IO: support block device type

FIP is accessed as memory-mapped type. eMMC is block device type.
In order to support FIP based on eMMC, add the new io_block layer.

io_block always access eMMC device as block size. And it'll only
copy the required data into buffer in io_block driver. So preparing
an temporary buffer is required.

When use io_block device, MAX_IO_BLOCK_DEVICES should be declared
in platform_def.h. It's used to support multiple block devices.

Fix computation of L1 bitmask in the translation table lib

This patch fixes the computation of the bitmask used to isolate
the level 1 field of a virtual address. The whole computation needs
to work on 64-bit values to produce the correct bitmask value.
XLAT_TABLE_ENTRIES_MASK being a C constant, it is a 32-bit value
so it needs to be extended to a 64-bit value before it takes part
in any other computation.

This patch fixes this bug by casting XLAT_TABLE_ENTRIES_MASK as
an unsigned long long.

Note that this bug doesn't manifest itself in practice because
address spaces larger than 39 bits are not yet supported in the
Trusted Firmware.

This patch puts the definition of `plat_get_syscnt_freq()`
under `#ifdef ARM_SYS_CNTCTL_BASE` in arm_common.c file.
This is the fix for compilation error introduced by commit-id
`749ade4`, for platforms that use arm_common.c but do not
provide a memory mapped interface to the generic counter.

Fixes ARM-software/tf-issues#395

Drop the current configuration options for selecting the location of
the ATF and TSP (ZYNQMP_ATF_LOCATION, ZYNQMP_TSP_RAM_LOCATION).
The new configuration provides one default setup (ATF in OCM,
BL32 in DRAM). Additionally, the new configuration options
- ZYNQMP_ATF_MEM_BASE
- ZYNQMP_ATF_MEM_SIZE
- ZYNQMP_BL32_MEM_BASE
- ZYNQMP_BL32_MEM_SIZE
can be used to freely configure the memory locations used for ATF and
secure payload.

Also, allow setting the BL33 entry point via PRELOADED_BL33_BASE.

This patch has the following change for rk3399.

* Set the uart to 115200 since the loader decide to set
uart baud to 115200Hz. So the ATF also should set uart baud to 115200.

* We need ensure the bl31 base is greater than 4KB since there are have
the shared mem for coreboot.(Note: the previous vesion was tested with uboot)

Otherwise, we will happen the exception crash since the ddr area won't
