arm-trusted-firmware-mvebu: switch to CZ.NIC's Secure Firmware
CZ.NIC as part of Turris project released free and open source WTMI application firmware wtmi_app.bin for all Armada 3720 devices. This firmware includes additional features like access to Hardware Random Number Generator of Armada 3720 SoC which original Marvell's fuse.bin image does not have. Add a patch which allows to pass the commit id, so the firmware is able to identify itself, see a04bffeb. Add a patch to disable linking with gold, since the ARM toolchain doesn't ship gold. Cherry-pick the 3 post-release fixes. Signed-off-by: Andre Heider <a.heider@gmail.com>

+Subject: [PATCH] wtmi: uart: fix UART baudrate divisor calculation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The UART code uses the xtal clock as parent for UART baudrate
+generation, but it assumes that xtal runs at 25 MHz, which isn't
+necessarily the case for all A3720 boards.
+
+Use get_ref_clk() to determine xtal clock rate.
+
+Use rounding division to compute the divisor value.

+Subject: [PATCH] avs: Validate VDD value from OTP
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+CPU VDD voltage value for 1.2 GHz frequency on some Espressobin boards is
+not set and raw value 0x00 is returned. In this case init_avs() function
+calculated CPU VDD voltage value to 0x00 + AVS_VDD_BASE = 0.898 V, which is
+too low for any operation and Espressobin board immediately crashed
+init_avs() function set this low value.
+
+This patch fixes above issue by validating returned VDD value from OTP and
+using default VDD value when invalid value is in OTP. With this patch
+init_avs() function does cause CPU crash anymore.
