sh: Remove sh7757lcr board

Browse Source 
This board has not been converted to CONFIG_DM by the deadline of v2020.01
and is missing other conversions which depend on this as well.  Remove it.

As this is the last SH4A board, remove that support as well.

/*
* SH-4A has support for unaligned 32-bit loads, and 32-bit loads only.
* Support for 64-bit accesses are done through shifting and masking
* relative to the endianness. Unaligned stores are not supported by the
* instruction encoding, so these continue to use the packed
* struct.
*
* The same note as with the movli.l/movco.l pair applies here, as long
* as the load is gauranteed to be inlined, nothing else will hook in to
* r0 and we get the return value for free.
*
* NOTE: Due to the fact we require r0 encoding, care should be taken to
* avoid mixing these heavily with other r0 consumers, such as the atomic
* ops. Failure to adhere to this can result in the compiler running out
* of spill registers and blowing up when building at low optimization
* levels. See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34777.

========================================
Renesas R0P7757LC0030RL board
========================================
This board specification:
=========================
The R0P7757LC0030RL(board config name:sh7757lcr) has the following device:
- SH7757 (SH-4A)
- DDR3-SDRAM 256MB (with ECC)
- SPI ROM 8MB
- 2D Graphic controller
- Ethernet controller
- eMMC 2GB
configuration for This board:
=============================
You can select the configuration as follows:
- make sh7757lcr_config
This board specific command:
============================
This board has the following its specific command:
- sh_g200
- write_mac
1. sh_g200
If we run this command, SH4 can control the G200.
The default setting is that SH4 cannot control the G200.
2. write_mac
You can write MAC address to SPI ROM.
Usage 1) Write MAC address
write_mac [ETHERC ch0] [ETHERC ch1] [GETHERC ch0] [GETHERC ch1]
For example)
=> write_mac 00:00:87:6c:21:80 00:00:87:6c:21:81 00:00:87:6c:21:82 00:00:87:6c:21:83
*) We have to input the command as a single line
(without carriage return)
*) We have to reset after input the command.
Usage 2) Show current data
write_mac
For example)
=> write_mac
ETHERC ch0 = 00:00:87:6c:21:80
ETHERC ch1 = 00:00:87:6c:21:81
GETHERC ch0 = 00:00:87:6c:21:82
GETHERC ch1 = 00:00:87:6c:21:83
Update SPI ROM:
============================
1. Copy u-boot image to RAM area.
2. Probe SPI device.
=> sf probe 0
8192 KiB M25P64 at 0:0 is now current device
3. Erase SPI ROM.
=> sf erase 0 80000
4. Write u-boot image to SPI ROM.
=> sf write 0x89000000 0 80000
