jlink: get flash and debug files from cli
Get BINFILE and ELFFILE from command line instead of environment variable.

Rename 'HEXFILE' to 'BINFILE' in the script as the binary file is used.
The documentation was already talking about 'BINFILE' but 'BINFILE'
was never exported by the build system and it was using 'HEXFILE' in the
implementation.

# Unified Segger JLink script for RIOT
#
# This script is supposed to be called from RIOTs make system,
# as it depends on certain environment variables. An
#
# Global environment variables used:
# JLINK: JLink command name, default: "JLinkExe"
# JLINK_SERVER: JLink GCB server command name, default: "JLinkGDBDerver"
# JLINK_DEVICE: Device identifier used by JLink
# JLINK_SERIAL: Device serial used by JLink
# JLINK_IF: Interface used by JLink, default: "SWD"
# JLINK_SPEED: Interface clock speed to use (in kHz), default "2000"
# FLASH_ADDR: Starting address of the target's flash memory, default: "0"
# JLINK_PRE_FLASH: Additional JLink commands to execute before flashing
# JLINK_POST_FLASH: Additional JLink commands to execute after flashing
#
# The script supports the following actions:
#
# flash: flash <binfile>
#
# flash given binary format file to the target.
#
# options:
# <binfile>: path to the binary file that is flashed
#
# debug: debug <elffile>
#
# starts JLink as GDB server in the background and
# connects to the server with the GDB client specified by
# the board (DBG environment variable)
#
# options:
# <elffile>: path to the ELF file to debug
# GDB_PORT: port opened for GDB connections
# TELNET_PORT: port opened for telnet connections
# DBG: debugger client command, default: 'gdb -q'
# TUI: if TUI!=null, the -tui option will be used
#
# debug-server: starts JLink as GDB server, but does not connect to
# to it with any frontend. This might be useful when using
# IDEs.
#
# options:
# GDB_PORT: port opened for GDB connections
# TELNET_PORT: port opened for telnet connections
#
# reset: triggers a hardware reset of the target board
