alps64: Fix for delay time for matrix scan
Delay less than 20us can cause false key detection in some situations.
With week internal pull-up takes time to charge stray capacitance of
trace between ground fill(and fingers), perhaps?
In particular, when testing Alps64 PCB without diodes tweezer is used
to close a key and this makes trace longer, more capacitance in result.
The bootkey set in bootloader_jump() works with Pro Micro and Leonardo.
This fix doesn't seem to prevent other bootloaders, however, it can be
disabled by defining NO_BOOTLOADER_CATERINA_BOOTKEY.

usb_usb: Add options for disabling blocking loops
USB startup wait loop delays UHS2 Task() starting for a while
like 200-600ms and USB suspend loop blocks the Task() while power
saving like 15-17ms. These loops may cause keyboard enumeration
failure, perhaps. Not confirmed it yet though.

lufa: Startup and suspend loop can be disabled
Startup wait loop is originally intended to start keyboard task loop and
after console output endpoint becomes available. But now that console
output is buffered when it is not available and you don't have to wait
for it to be ready. You can disable the startup wait loop by defining
NO_WAIT_FOR_USB_CONFIGURED in config.h
Suspend loop is used for power saving by making tasks stop while
USB bus is under suspend status. But this may cause problem on some
devices like converter that must keep doing its task to retain
communication with keyboard. The suspend loop can block its task for
around 15-17ms. You can disable the suspend loop by defining
NO_USB_SUSPEND_LOOP in config.h.

usb_usb: Order of init prevents uneeded bus reset
Device classes are registered to array of config driver pool and
tried in that order until proper class is found in configuration process.
If tried driver cannot handle device, bus reset is issued to the device.

lufa: Fix for freeze at re/boot time problem
Calling led_set() in ISR can cause the problem. With converter
especially, led_set() can take long time and USB can be stuck in the end.
USB-USB converter freezes occasionally when computer power up or reboot.

Correct the comments of matrix ROW and COL. (#604)
according to the code:
static uint8_t matrix[MATRIX_ROWS];
#define ROW(code) (code>>3)
#define COL(code) (code&0x07)
in converter/terminal_usb/matrix.c
ROW is decided by bits 7-4 of scancode
COL is decided by bits 2-0 of scancode

lufa: usb-usb: Use LUFA startup instead of cusotom
- Change keyboard_init() timing and matrix_scan() is called in USB
startup wait loop for FC660C
- FC660C startup seems to be faster and it doesn't work without this fix
