riscv: Rename Andes cpu and board names
The current ae350-related defconfigs could also
support newer Andes CPU IP, so modify the names of CPU
from ax25 to andesv5, and board name from ax25-ae350 to ae350.

+AE350
+======
+
+AE350 is the mainline SoC produced by Andes Technology using AndesV5 CPU core
+based on RISC-V architecture.
+
+AE350 has integrated both AHB and APB bus and many periphals for application
+and product development.
+
+AndesV5 is Andes CPU IP family that adopts RISC-V architecture.
+
+AndesV5 family includes 25, 27, 45 series.
+

+
+Build and boot steps
+--------------------
+
+Build:
+
+1. Prepare the toolchains and make sure the $PATH to toolchains is correct.
+2. Use `make ae350_rv[32|64]_defconfig` in u-boot root to build the image for
+ 32 or 64 bit.
+
+Verification:
+
+1. startup
+2. relocation
+3. timer driver
+4. uart driver
+5. mac driver
+6. mmc driver
+7. spi driver
+
+Steps
+-----
+
+1. Ping a server by mac driver
+2. Scan sd card and copy u-boot image which is booted from flash to ram by sd driver
+3. Burn this u-boot image to spi rom by spi driver
+4. Re-boot u-boot from spi flash with power off and power on

+Running U-Boot SPL
+------------------
+The U-Boot SPL will boot in M mode and load the FIT image which include
+OpenSBI and U-Boot proper images. After loading progress, it will jump
+to OpenSBI first and then U-Boot proper which will run in S mode.
+
+
+How to build U-Boot SPL
+-----------------------
+Before building U-Boot SPL, OpenSBI must be build first. OpenSBI can be
+cloned and build for AE350 as below:
+
+.. code-block:: none
+
+ git clone https://github.com/riscv/opensbi.git
+ cd opensbi
+ make PLATFORM=andes/ae350
+
+Copy OpenSBI FW_DYNAMIC image (build/platform/andes/ae350/firmware/fw_dynamic.bin)
+into U-Boot root directory
+
+
+How to build U-Boot SPL booting from RAM
+----------------------------------------
+With ae350_rv[32|64]_spl_defconfigs:
+
+U-Boot SPL will be loaded by gdb or FSBL and runs in RAM in machine mode
+and then load FIT image from RAM device on AE350.
+
+
+How to build U-Boot SPL booting from ROM
+----------------------------------------
+With ae350_rv[32|64]_spl_xip_defconfigs:
+
+U-Boot SPL can be burned into SPI flash and run in flash in machine mode
+and then load FIT image from SPI flash or MMC device on AE350.
