There is an easy default implementation of spi_master_block_write that
just calls spi_master_write in a loop, so the default implementation
of spi_master_block_write has been added to all targets.
Modifying the code for mbed ci shield test -> analogin_api.c, W7500x_adc.c, gpio_irq_api.c, W7500x_gpio.c
Modifying the code for fix bug -> W7500x_uart.c(register control driver problem), W7500x_uart.h, pinmap.c(pullup, pulldown problem)
Add sleep/deepsleep functions to platform layer which are replacing HAL
functions with the same name, rename existing symbols in HAL layer
to hal_sleep/hal_deepsleep. This way sleep functions
are always available, even if target doesn't implement them, which makes
the code using sleep clearer. It also enables us to make decision on in
which builds (debug/release) the sleep will be enabled.
