reason:
1 On different architectures, we can utilize more optimized strategies
to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

All modern desgin support stack pointer and it's also an
important information, so let's standardize this interface.

To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG. The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.
1. Serial (UART) driver (13 ports)
2. Ethernet driver
This port is provided on two boards
1. RSK RX65N-2MB
2. GR-Rose
The port is built on Cygwin environment.
As part of this port, we have created two documents
1. Readme.txt for each board
2. User manual to provide information about development environment setup
Both these documents are placed under
1. /boards/renesas/rx65n/rx65n-grrose
2. /boards/renesas/rx65n/rx65n-rsk2mb
We have run 'nxstyle' for coding guidelines and 'ostest' for testing NuttX features on test platform.
We have shared the log with no errors as confirmation of valid port.
