Should be (note the commented line):

void Adafruit_TFTLCD::pushColors(uint16_t *data, uint8_t len, boolean first) {
uint16_t color;
uint8_t hi, lo;
CS_ACTIVE;
if(first == true) { // Issue GRAM write command only on first call
CD_COMMAND;
if(driver == ID_932X) write8(0x00);
if ((driver == ID_9341) || (driver == ID_HX8357D) || (driver == ID_ILI9327)){
write8(0x2C);
} else if (driver == ID_S6D0154){
write8(0x22);
} else {
write8(0x22);
}}
CD_DATA;
while(len--) {
color = *data++;
hi = color >> 8; // Don't simplify or merge these
lo = color; // lines, there's macro shenanigans
write8(hi); // going on.
write8(lo);
}
CS_IDLE;
//}
}

Due port/pin : PC23 PC24 PB27 PC26 PD7 PC29 PC21 PC22 -> did not worked for me. After referring the pin-out, I corrected the code to refer
Due port/pin : PC23 PC24 PC25 PC26 PC28 PB25 PC21 PC22

After making corresponding changes, it worked!!!

The revised code is

#define write8inline(d) { \

PIO_Clear(PIOC, (((~d) & 0x01)<<(22-0)) | (((~d) & 0x02)<<(21-1)) | (((~d) & 0x08)<<(28-3)) | (((~d) & 0x10)<<(26-4)) | (((~d) & 0x20)<<(25-5)) | (((~d) & 0x40)<<(24-6)) | (((~d) & 0x80)<<(23-7)) );
PIO_Set(PIOB, (((d) & 0x04)<<(25-2)));
PIO_Clear(PIOB, (((~d) & 0x04)<<(25-2)));
WR_STROBE; }
