Tetsuya Uemura f5d1d22f25 nxprtc: Fix timing issue with register access. 
My Adafruit PCF8523 RTC on either RPi2B or RPi3B+ failed to work around
80 ~ 90 % of boot-ups, by printing the following log lines.

nxprtc0: <NXP PCF8523 RTC> at addr 0xd0 on iicbus0
nxprtc0: cannot set up timer
Warning: no time-of-day clock registered, system time will not be set accurately

This is due to pcf8523_start_timer(sc) returned non-zero in
nxprtc_start() due to a register read failure of PCF8523_R_TMR_A_FREQ or
PCF8523_R_TMR_CLKOUT or a failure to program a new value.

The pause_sbt("nxpbat") sleep was too short and caused the register
access failures.
